Upon cancellation of the secondary circuit, the secondary piston rests on the limiter at the end of the opening of the cylinder, then the pressure rises in the primary circuit (II) (Fig. 6.5).

anti-lock braking system MK60

ESP is currently the most modern active control system and prevents the emergence of critical situations in the movement at the beginning.

Anti-lock braking system ESP MK60 Astra-H includes the following systems: - Anti-lock braking system (ABS system); - Traction Control System (TCS); - Program electronic stability control (ESP). and has the following main functions: - Logical control scheme understeer (UCL); - Control braking force when the motion in the rotation (CBC); - Trailer stability control program (TSP); - Integral control body (ICC). Depending on the version of equipment, anti-lock braking system ESP MK60 may also have the following additional features: - Detection system pressure drops (DDS) controls the loss of tire pressure through the wheel speed sensors in the event of loss of tire pressure monitoring (TPMS / DDS). - Hydraulic power Brake Assist (HBA); - Assistance when starting on a slope (HSA) to prevent slipping back into the car for two seconds, thus facilitating moving off on a slope. The following table contains general information about using different versions of systems installed in vehicles Astra-H.

Service

The anti-lock braking system ESP MK60 / HSA, a control unit can not be separated from the hydraulic modulator. The control unit anti-lock braking / hydraulic modulator should always be replaced as a single unit.

Description connectors - anti-lock braking system ESP MK60

unit

The control unit is an anti-lock braking system is connected to a power source through a wiring harness connector with 26 contacts, which Pin below.

Sensor / group yaw angular velocity

Yaw angular velocity sensor is installed on the Astra-H, together with the control system ABS ESP MK60. This sensor calculates the instantaneous speed of the vehicle yaw rate (angular velocity) and lateral acceleration. These data require a power control anti-lock braking system for calculating the beginning of the critical traffic situations.

Yaw angular velocity sensor has its own diagnostic tool. It is controlled by a control unit antilock braking system, ie, the control unit antilock braking system receives information on all faults yaw angular velocity sensor via a private bus HS CAN. The corresponding fault codes stored in the control unit anti-lock braking system, with activated warning lights.

-Lock braking system ESP MK70

Fig. 6.10. Schematic diagram of the anti-lock braking system MK70

Anti-lock brake system MK70 is a simple anti-lock brake system with diagonal contours. This is - the further development of anti-lock braking system MK60. The control unit is an anti-lock braking system / power hydraulic modulator has been optimized for weight, its dimensions were reduced. The four active sensors, mounted on wheels car supply control unit of anti-lock brakes with necessary information about the speed of rotation. If set, the control unit anti-lock braking system communicates with the hydraulic modulator and can not be disconnected from the modulator, it requires lift hydraulic modulator assembly with the control unit.
