Abstract
In a vehicle having an ABS control system, a braking control of a right and left rear wheels can be independently carried out when a lateral acceleration exceeds a lateral acceleration value set beforehand. When the ABS control is operated at one of the right and left rear wheels, the control system executes a stepwise pressure increase control which provides a stepwise pressure increase for the other rear wheel up to a braking pressure to be reached at a start of the control.
Claims8
A braking force control system of a vehicle, comprising:
- a lateral acceleration detecting unit detecting a lateral acceleration of the vehicle;
- and
- a braking control unit carrying out an anti-lock braking control and carrying out an independent braking control of right and left rear wheels,
- wherein, in a case that said lateral acceleration exceeds a lateral acceleration value set beforehand, when said anti-lock braking control is operated at one of the right and left rear wheels, said braking control unit executes a stepwise pressure increase control for providing a stepwise pressure increase for the other rear wheel up to a braking pressure to be reached at a start of the control.
A braking force control system of a vehicle, comprising:
- a lateral acceleration detecting unit detecting a lateral acceleration of the vehicle;
- and
- a braking control unit carrying out an anti-lock braking control and carrying out an independent braking control of right and left rear wheels,
- wherein said braking control unit executes a braking force distribution control between front and rear wheels as specified when said lateral acceleration exceeds a lateral acceleration value set beforehand, and said braking control unit stops said front and rear braking force distribution control of either one of rear wheels and executes a stepwise pressure increase control thereof when said anti-lock braking control is operated at the other rear wheel, said stepwise pressure increase control providing a stepwise pressure increase up to a braking pressure to be reached at a start of the control.
A braking force control method of a vehicle having a braking control unit carrying out an anti-lock braking control and carrying out an independent braking control of right and left rear wheels, said method comprising the steps of:
- detecting a lateral acceleration of the vehicle;
- and
- executing, when said anti-lock braking control is operated at one of the right and left rear wheels, a stepwise pressure increase control for providing a stepwise pressure increase for the other rear wheel up to a braking pressure to be reached at a start of the control, in a case that said lateral acceleration exceeds a lateral acceleration value set beforehand.
A braking force control method of a vehicle having a braking control unit carrying out an anti-lock braking control and carrying out an independent braking control of right and left rear wheels, said method comprising the steps of:
- detecting a lateral acceleration of the vehicle;
- and
- executing a braking force distribution control between front and rear wheels as specified when said lateral acceleration exceeds a lateral acceleration value set beforehand;
- and
- executing, when said anti-lock braking control is operated at one of the right and left rear wheels, a stepwise pressure increase control of the other rear wheel after stopping said front and rear braking force distribution control thereof, said stepwise pressure increase control providing a stepwise pressure increase up to a braking pressure to be reached at a start of the control.
