In cases where the speedometer is electronic, the signal from the speedometer transducer is also used to provide the feedback siglJ to the ECU, An alternative type of sensor uses permanent magnets glued to the drive shaft to generate an a.
c, pulse in a pick-up coil situated adjacent to the drive shaft. Whereas some speed transducers generate an analogue signal voltage which rises proportional to speed: Applications I I command speed-"""7"" c signal control unit engine Fig.
In the latter case an increase in speed produces logic level pulses the number of which is in proportion to the speed. Control IInit This unit is the brain of the system; it.
provides an output signal to the actuator to adjust the throttle whenever it detects the actual speed of the vehicle is above or below that set by the driver, The closed-loop controller fitted in the control unit compares the system's output measured by the sensor to that indicated as an input command, Difference between the two signals, obtained by simple subtraction, is called an error signal; this is used to adjust the control signal so that it is proportional to the error signal.
A proportional control system by itself lacks sensitivity since a comparatively large error signal is required to make final adjustments to the speed, To overcome this Problem, vehicle speed controllers generally use a proportional-integral system as shown in Figure In this diagram it will be seen that the command signal is the sum of the outputs from the two blocks A and B.
The circuit of the proportional block A gives 'an output that is in proportion to the error signal, whereas the integral block B produces a variable-rate output designed to reduce the error to zero in a short time without oscillation.
The cruise-control system can be designed for analogue or digital operation, The analogue system uses a capacitor charge set by the driver by the switch operation to represent vehicle speed. Detection of the charge on the capacitor is achieved by a very high input impedance amplifier; this outputs ;1 voltage to all error.
unplifier to represent the command speed. A digital circuit stores the input speed command and the vehicle speed as numbers. Feedback pulses from the sensor are counted against a clock signal and these arc subtracted from he command speed pulse to obtain the error number.
This is then passed through the two paths previously outlined. Alternatively, the error signal can be fed to a microcomputer for processing, so with this method of control a more sophisticated programme can be used.
Data in ; digit:d sysrcn: is stored in the form of digital codes: compared with an analogue controller, the digital system is less affected by changes in temperature and humidity. Fault diagnosis Electronic operation of this ,YSI'l'1l1 is similar to many other sensor-ECU-actuator systcrns, so fault diagnosis is carried out in a similar manner.
Many systems have a cruise indicator lamp on the instrument panel that illuminates when the system is in operation. If the self-diagnosis facility detects a malfunction, the lamp blinks to alert the driver; at the same time the fault is memorized by the cruise control ECU.
By following a given test sequence the tech. nician is able to see from the lamp signal pattern if each part is functioning correctly. because far too many factors are involved. fil ~ rear wheels of tractor locking and trailer swing trailer wheels locking.

A main difference between the light and heavy vehicles is the type of brake system to which the ADS layout is added, Heavy vehicles use compressed air to operate the brake system, whereas a light vehicle has a hydraulic brake system, This means that although the electronic control system is similar, the method of control of the automltive brake system is different.
Hydraulic brake ABS components The layout of a typical ABS unit for a rear-wheel-drive car is shown in Figure 2. Wheel-speed sensors Normally three wheel sensors are fitted: one to each non-driving wheel and one to the propeller shoft flange on tlw axi!? At this instant.

Fluid released from an individual line flows to an accumulator. This is a chamber fitted with a spring-loaded piston which temporarily stores hydraulic pressure so that it can be re-supplied to the brake line if the ECU signals that extra fluid pressure to needed. Return of fluid to the lines via the ~CClIrnulator is achieved by a pump.

For further information about the mechanical details of an ABS system see Fundamentals oj Motor Vehicle Technology. In this event the system reduces automltive fluid pressure in the common rear brake line with the result that the total braking torque of the rear wheels is diminished.
Most modern vehicles overcome this problem by using a 4-cltallllel system; this provides each wheel with electrobics own sensor and independent fluid line. A further improvcmcut is the total enclosure of each wheel sensor; this reduce's the risk of damage due to dirt or impact.
ECU operation The digital COli troller consists of an input amplifier, computil1g unit, power stage and monitoring unit. Input amplifier This unit filters and reshapes the a. waves from the sensors into rectangular pulses suitable for operating the computer.

This effect is due to the rapid on-off action of the ABS system. An ABS warning lamp on the instrument panel shows when the ABS system is in use. a few seconds to show that the system is in order. Any ABS fault detected by the self-diagnosing facility is stored as a code in the memory unit and signalled to the driver by the warning light. Technicians can identify any stored faults in the normal way, for example by using either a code reader or by observing the warning lamp to establish the blinking code. In the past, these operating units relied on a collection of mechanical cables, rods and levers to sense the operating conditions of the engine and vehicle. Modern electronics have made these clumsy sensing and control systems obsolete, but hydraulic actuaeion of the planetnry genr-set. clutches and brakes is still retained. Much of the information required to ge a gearbox is already available when electronics are used to manage an engine. This data includes information engine speed and load as well as vehicle speed. Basic system The layout shown in Figure o road speed In this system the ECU is programmed to control the gear changes in response to data received from various input sensors, especially those giving a feedback of load and speed. Since this feedback is readily available, the system can easily be converted to achieve closed-loop control. On many systems that use this layout, the actuator is a solenoid-controlled ball valve fitted in the hydraulic circuit to control gear changes. Two or three of these valves are used to provide the various gears. Modern systems Today, an electronically controlled transmission ECT incorporating an intelligent management system takes int. These patterns are selected by an ECT switch situated next to the gear selector; the position of the switch indicated ' on the instrument panel by n signAl lomp. Electronic control "nit Since data frorn some sensors is needed both by the engine and transmission unit, the advent of new powerful processors has allowed designers to use a single ECU to manage both units.

Some faults an: identified by a blink code; other fault codes stored in the memory need to be down-loaded to an off-board code reader for interpretation. When a wheel spins, traction is lost and vehicle control is jeopardized. This control problem arises because spinning of a rear wheel causes the back of the vehicle to move sideways and loss of adhesion at the front results in a loss of steering control. Since many vehicles are now fitted with ABS, the speed sensors on each wheel can also be used to signal when a wheel starts to spin. The existence on the vehicle of this sensing equipment means that it is a comparatively small step to a tractive control system TCS. This fact suggests that new luxury vehicles are likely to incorporate a traction control system. o,peration ,issigrial1~d by a panel lamp -- TCS system layout The similarity between the construction of a tractive control system and an anti-lock braking system issho~ in Figure Throttle controller Engine torque is controlled either by fitting an additional throttle. electronically controlled or using an actuator on the main throttle simi1a~ t~' th~t' employed for cruise control. Vehicles fitted with this electronic throttle control system have the accelerator pedal connected to a potentiometer; this sends to the ECU an 'a'naI6gtii voltage signal which increases as the pedal is depressed. Traction control ECU The TCS control unit constantly receives signals from the four speed sensors; this data allows it to calculate t. ie speed of each wheel. When the accelerator pedal is depressed sufficient to cause wheel spin at any wheel, the ECU senses chat the wheel is turning faster than the target speed. This causes it to partly close the throttle and, using llie AilS control. slightly applies the brake on the spinning wheel until its speed is reduced to the target speed.
