Abstract
A braking system for a vehicle in which, when a brake pedal is depressed, a corresponding braking effect is generated. The system includes an operating device which is in operative connection with an accelerator pedal, for setting a desired deceleration. When the accelerator pedal is released, the braking system brakes the vehicle corresponding to the set desired deceleration.
Claims15
A braking system for a vehicle having a brake pedal, depression of which generates a corresponding braking effect, said system comprising:
- an operating device for setting a desired deceleration;
- an accelerator pedal;
- a control unit coupled in communication with said operating device and with a sensor for detecting depression and release of said accelerator pedal;
- wherein,
- in response to a release of the accelerator pedal by a driver, the control unit causes the braking system to brake the vehicle with a deceleration corresponding to the set desired deceleration;
- and
- said control unit includes means for changing from controlling vehicle deceleration to controlling brake pressure, when vehicle speed falls below a preset value.
A braking system for a vehicle having a brake pedal, depression of which generates a corresponding braking effect, said system comprising:
- an operating device for setting a desired deceleration;
- an accelerator pedal;
- a control unit coupled in communication with said operating device and with a sensor for detecting depression and release of said accelerator pedal;
- wherein,
- when the accelerator pedal is released, the control unit causes the braking system to brake the vehicle with a deceleration corresponding to the set desired deceleration;
- and
- said control unit includes a memory for storing at least one buildup curve for controlling a build up of brake pressure in response to a release of said brake pedal, said buildup curve being a function of a vehicle operating parameter, and corresponding to an adjustable desired deceleration.
A method for operating a vehicle brake system having an accelerator pedal, and a brake pedal that can be depressed to generate a corresponding braking effect, said method comprising:
- a vehicle driver manipulating an operating device for selecting a desired vehicle deceleration;
- in response to a release of the accelerator pedal by said driver, said brake system braking the vehicle with a deceleration corresponding to the desired deceleration;
- and
- changing from controlling vehicle deceleration to controlling brake pressure when vehicle speed falls below a preset value.
A method for operating a vehicle brake system having an accelerator pedal, and a brake pedal that can be depressed to generate a corresponding braking effect, said method comprising:
- a vehicle driver manipulating an operating device for selecting a desired vehicle deceleration;
- in response to a release of the accelerator pedal by said driver, said brake system braking the vehicle with a deceleration corresponding to the desired acceleration;
- and
- controlling a buildup of brake pressure responsive to a release of the brake pedal, according to a pressure buildup curve stored in a memory, said pressure buildup curve corresponding to an adjustable desired deceleration, which is a function of at least one vehicle operating parameter.
