Abstract
In one aspect, a vehicle control apparatus, a vehicle control method, and a vehicle control system according to the present invention acquire control conditions including at least one of information about a running environment and information about a motion state of a vehicle in a preview area ahead on a running path on which the vehicle is running, start outputting control commands for generating a vehicle behavior based on the control conditions before the vehicle reaches the preview area, and stop outputting the control commands when the vehicle enters the preview area. In this way, an occupant in the vehicle can easily assume a posture in preparation for change in running environment or motion state of the vehicle.
Claims5
A vehicle control apparatus comprising:
- a control unit that outputs a result calculated based on input information,
- wherein the control unit acquires information about an estimated lateral acceleration calculated based on a curvature of a running path on which the vehicle is running and a speed of the vehicle in a preview area ahead on the running path, starts outputting control commands to a driving apparatus and a braking apparatus included in the vehicle for generating a roll behavior based on the estimated lateral acceleration before the vehicle reaches the preview area, and stops outputting the control commands when the vehicle enters the preview area, and
- wherein the control unit outputs the control commands to the driving apparatus and the braking apparatus such that driving force generated by the driving apparatus and braking force generated by the braking apparatus change more slowly at a start of the output of the control commands than at an end of the output of the control commands.
A vehicle control apparatus comprising:
- a control unit that outputs a result calculated based on input information,
- wherein the control unit acquires information about an estimated lateral acceleration calculated based on a curvature of a running path on which the vehicle is running and a speed of the vehicle in a preview area ahead on the running path, starts outputting control commands for generating a roll behavior based on the estimated lateral acceleration before the vehicle reaches the preview area, and stops outputting the control commands when the vehicle enters the preview area, and
- wherein the control unit outputs the control commands on a condition that a duration time of a straight-running state of the vehicle determined based on a steering angle of the vehicle exceeds a threshold.
A vehicle control method comprising:
- acquiring, by a control unit mounted in a vehicle, information about an estimated lateral acceleration calculated based on a curvature of a running path on which the vehicle is running and a speed in a preview area ahead on the running path;
- starting, by the control unit, outputting control commands for generating a roll behavior based on the estimated lateral acceleration before the vehicle reaches the preview area;
- and
- stopping, by the control unit, outputting the control commands when the vehicle enters the preview area;
- and
- outputting, by the control unit, the control commands on a condition that a duration time of a straight-running state of the vehicle determined based on a steering angle of the vehicle exceeds a threshold.
