Abstract
In a method for automatically adjusting the vehicle speed of a vehicle, while the distance to a preceding other vehicle is continuously measured, in order to reduce an initial distance, the vehicle is initially moved, in a drive phase, at a higher vehicle speed and is subsequently decelerated in a braking phase.
Claims16
A method for automatically adjusting a speed of a first vehicle while a distance of the first vehicle to a second vehicle that leads the first vehicle is continuously measured, the method comprising:
- responsive to the distance being a first distance that is greater than a setpoint distance, reducing the distance from the first distance to the setpoint distance by:
- in a drive phase, a processor driving the first vehicle at a higher vehicle speed than the second vehicle;
- and
- in a braking phase that is subsequent to the drive phase, the processor initiating and then maintaining a deceleration of the first vehicle using at least one of friction and a generator mode of an electric motor situated in a drive train of the vehicle until the distance equals the setpoint distance and the speeds of the first and second vehicles match.
A system comprising a control unit with an interface by which the processor can control a first vehicle, wherein the control unit is configured to perform a method for automatically adjusting a speed of the first vehicle while a distance of the first vehicle to a second vehicle that leads the first vehicle is continuously measured, the method comprising:
- responsive to the distance being a first distance that is greater than a setpoint distance, reducing the distance from the first distance to the setpoint distance by:
- in a drive phase, controlling the first vehicle to drive at a higher vehicle speed than the second vehicle;
- and
- in a braking phase that is subsequent to the drive phase, initiating and then maintaining a deceleration of the first vehicle using at least one of friction and a generator mode of an electric motor situated in a drive train of the vehicle until the distance equals the setpoint distance and the speeds of the first and second vehicles match.
A first vehicle comprising a system that includes a sensor and a control unit communicatively coupled to the sensor, wherein the control unit is configured to perform a method for automatically adjusting a speed of the first vehicle while a distance of the first vehicle to a second vehicle that leads the first vehicle is continuously measured by the sensor, the method comprising:
- responsive to the distance, as indicated by a signal of the sensor, being a first distance that is greater than a setpoint distance, reducing the distance from the first distance to the setpoint distance by:
- in a drive phase, controlling the first vehicle to drive at a higher vehicle speed than the second vehicle;
- and
- in a braking phase that is subsequent to the drive phase, initiating and then maintaining a deceleration of the first vehicle using at least one of friction and a generator mode of an electric motor situated in a drive train of the vehicle until the distance equals the setpoint distance and the speeds of the first and second vehicles match.
