Abstract
The invention discloses an automatic brake system for motor vehicles which serves to shorten the stopping distance by means of propulsion motor vehicle control signals while simultaneously lowering the required costs. According to the invention, means are provided which ensure pre-filling of the wheel brakes when a control signal which represents the motion of the gas pedal when the actuating force is discontinued is received by the brake system control unit.
Claims27
Automatic brake system for motor vehicles operated by a vehicle driver, said vehicle of the type having wheel brakes that are assigned to the motor vehicle wheels, comprising:
- an electronic control unit that receives at least one control signal from a device for detecting the discontinuation of an actuating force applied on the gas pedal, the foot throttle or the twist grip throttle of the motor vehicle by the vehicle driver,
- means for ensuring pre-filling of the wheel brakes when the control signal occurs wherein the control signal represents the load status of the motor vehicle engine wherein the control signal represents at least one of a change in the presence in the intake manifold of the engine or a change in the back pressure in the exhaust system.
Automatic brake system for motor vehicles, with wheel brakes that are assigned to the motor vehicle wheels, comprising:
- an electronic control unit that receives at least one control signal from a device for detecting the discontinuation of an actuating force applied on the gas pedal, the foot throttle or the twist grip throttle of the motor vehicle by the driver,
- means for ensuring pre-filling of the wheel brakes when the control signal occurs wherein the control signal represents the load status of the motor vehicle engine wherein the control signal is derived from performance characteristics stored in a control device of the fuel injection system wherein a fuel injection interrupt signal is used as the control signal.
Automatic brake system for motor vehicles, with wheel brakes that are assigned to the motor vehicle wheels, comprising:
- an electronic control unit that receives at least one control signal from a device for detecting the discontinuation of an actuating force applied on the gas pedal, the foot throttle or the twist grip throttle of the motor vehicle by the driver,
- means for ensuring pre-filling of the wheel brakes when the control signal occurs wherein the control signal represents the load status of the motor vehicle engine wherein the control signal is derived from performance characteristics stored in a control device of the engine ignition system.
Automatic brake system for motor vehicles, with wheel brakes that are assigned to the motor vehicle wheels, comprising:
- an electronic control unit that receives at least one control signal from a device for detecting the discontinuation of an actuating force applied on the gas pedal, the foot throttle or the twist grip throttle of the motor vehicle by the driver,
- means for ensuring pre-filling of the wheel brakes when the control signal occurs wherein the control signal represents the load status of the motor vehicle engine wherein the control signal represents the decrease in the engine speed wherein the control signal is generated by a crankshaft speed sensor.
Automatic brake system for motor vehicles, with wheel brakes that are assigned to the motor vehicle wheels, comprising:
- an electronic control unit that receives at least one control signal from a device for detecting the discontinuation of an actuating force applied on the gas pedal, the foot throttle or the twist grip throttle of the motor vehicle by the driver,
- means for ensuring pre-filling of the wheel brakes when the control signal occurs wherein the control signal represents the load status of the motor vehicle engine wherein the control signal represents the decrease in the engine speed wherein the control signal is generated by an idle switch that is assigned to the fuel injection pump.
Automatic brake system for motor vehicles, with wheel brakes that are assigned to the motor vehicle wheels, comprising:
- an electronic control unit that receives at least one control signal from a device for detecting the discontinuation of an actuating force applied on the gas pedal, the foot throttle or the twist grip throttle of the motor vehicle by the driver,
- means for ensuring pre-filling of the wheel brakes when the control signal occurs said electronic control includes means for receiving a second control signal that is generated by a device for detecting when the driver's foot contacts the brake pedal further including means for measuring the time elapsed between the beginning of the pre-filling process and the reception of the second control signal and compare the measured value to a predetermined value.
