21.3. Electronic system of stabilisation of course stability (ESP)

By means of stabilisation system dynamics of the car in limiting modes is supervised, for example at passage of turns on high speed. Danger of a pulling down or car drift essentially decreases at any condition of a road covering.
In electronic system of stabilisation are integrated antiblocking and пробуксовочная systems. ESP in addition measures speed of moving of a body round a vertical axis, acceleration in a cross-section plane, pressure in system of a drive of brakes and an angle of rotation of operated wheels. On the basis of the data about an angle of rotation of operated wheels and speed of the car the system defines a direction in which the driver of the car intends to move, and compares with an actual direction of movement. At a nonagreement of these factors when the pulling down or car drift begins, the stabilisation system automatically brakes a certain wheel.
In the presence of malfunction the electronic control system is automatically disconnected, thus in a combination of devices control lamps light up. In this case the brake system works in a usual mode.

Fig. 15–1. An arrangement on the car of elements of antiblocking system of brakes and electronic system of stabilisation (ABS/ESP): 1 – the hydraulic pump; 2 – the pressure gauge in brake system; 3 – the relay of pump J105 for system Bosch 5.3; 4 – the electromagnetic relay of valve J106 for system Bosch 5.3; 5 – hydraulic block N55 with the block of management J104; 6 – the block of management J104 for system Bosch 5.0; 7 – the gauge of level of a brake liquid – F34; 8 – a rotor of forward right gauge ABS; 9 – forward right gauge ABS – G45; 10 – the block of management J104 (with ESP); 11 – the gauge of angle of rotation G85 (with ESP); 12 – the switch for systems TCS/ESP-E132; 13 – the gauge of angle of rotation G85; 14 – the switch of a control lamp of a condition of lay brake F9; 15 – a rotor of back right gauge ABS; 16 – back right gauge ABS – G44; 17 – back left gauge ABS – G46; 18 – a rotor of back left gauge ABS; 19 – the lateral gauge of acceleration G200; 20 – the gauge of condition G202; 21 – the relay of pump J105 for system Bosch 5.3; 22 – electromagnetic relay J106 for system Bosch 5.3; 23 – control lamp K118; 24 – control lamp ABS – K47; 25 – a control lamp of a condition of a lay brake – K14; 26 – control bulb TCS/ESP – K86; 27 – the switch of stoplight F; 28 – a rotor of forward left gauge ABS; 29 – forward left gauge ABS – G47



The arrangement of elements ABS and ESP on the car and a forward axis is shown on fig. 15–1 and 15–2.

Fig. 15–2. An arrangement of elements ABS/ESP on a forward axis: 1 – a shaft of a drive with gauge ABS rotor (if gauge ABS rotor is damaged, it is necessary to replace the external hinge of a shaft of a drive); 2 – a bolt, 10 Н·м; 3 – an arm for fastening of a wire of gauge ABS with a sealing ring; 4 – a bolt; 5 – the tightening plug; 6 – consolidation; 7 – gauge ABS
