Abstract
A method and a system for decelerating a single-track motor vehicle, includes using a control unit to determine a total torque of a wheel of the motor vehicle required for a desired riding maneuver, in particular a controlled slip of a rear wheel, determine, a braking partial torque and a motor partial torque as a function of the total torque required, and generate the braking partial torque on the wheel by controlling a brake system of the motor vehicle and generating the motor partial torque on the wheel by controlling a motor of the motor vehicle The invention further includes a single-track motor vehicle configured to execute the decelerating method.
Claims14
A method for decelerating a single-track motor vehicle, comprising the acts of:
- determining, using a control unit of the motor vehicle, a total torque of a rear wheel of the motor vehicle required to induce a controlled overbraking of the rear wheel to intentionally induce a slide of the motor vehicle at least during initial braking for a curve;
- determining, using the control unit, a braking partial torque and an engine partial torque using the control unit based on total torque;
- and
- generating, using the control unit, the braking partial torque at the rear wheel by activating a braking system of the motor vehicle and the engine partial torque at the rear wheel by activating an engine of the motor vehicle to induce the controlled overbraking of the rear wheel.
A single-track motor vehicle, comprising:
- a front wheel;
- a rear wheel;
- a braking system having a front wheel brake and a rear wheel brake;
- an engine;
- at least one sensor system;
- and
- a control unit coupled to the braking system, the engine, and the sensor system,
- wherein the control unit is configured to:
- determine a total torque of a rear wheel of the motor vehicle required to induce a controlled overbraking of the rear wheel to intentionally induce a slide of the motor vehicle at least during initial braking for a curve;
- determine a braking partial torque and an engine partial torque based on total torque;
- and
- generate the braking partial torque at the rear wheel by activating the braking system of the motor vehicle and the engine partial torque at the rear wheel by activating the engine of the motor vehicle to induce the controlled overbraking of the rear wheel.
A method for decelerating a single-track motor vehicle, comprising the acts of:
- determining, using a control unit of the motor vehicle, a total torque of a wheel of the motor vehicle required for a desired driving maneuver using a control unit of the motor vehicle;
- determining, using the control unit, a braking partial torque and an engine partial torque using the control unit based on total torque;
- and
- generating, using the control unit, the braking partial torque at the wheel by activating a braking system of the motor vehicle and the engine partial torque at the wheel by activating an engine of the motor vehicle,
- wherein generating the braking partial torque at the wheel includes:
- determining, using the control unit, a setpoint brake pressure of the braking system corresponding to the ascertained braking partial torque, and
- generating the braking partial torque by actuating the brake of the braking system using the brake controller to obtain the determined setpoint brake pressure.
