Abstract
An automated parking movement path is generated such that a vehicle speed and a steering angle are set so as to enable a full steering axial force to be applied within a range of being less than a maximum driving force which depends on the temperature of a steering motor. Consequently, a load on the steering motor is suppressed, and thus a rise in the temperature of a steering motor is suppressed within the movement path from a movement starting position to a movement ending position.
Claims4
A vehicle control device configured to cause a user's own vehicle to be automatically parked inside a parking space, based on outputs of external environment sensors provided in the user's own vehicle,
- the vehicle control device comprising:
- a temperature sensor configured to detect a temperature of a steering motor;
- and
- one or more processors that execute computer-executable instructions stored in a memory,
- wherein the one or more processors execute the computer-executable instructions to cause the vehicle control device to:
- select the parking space;
- generate a movement path for parking from a starting position of parking to a position inside the selected parking space;
- and
- control a propulsion device and the steering motor along the generated movement path, and
- wherein the steering motor generates a driving force based on a steering instruction from the vehicle control device and applies a steering axial force to a rack shaft to thereby cause vehicle wheels to be steered, and
- when generating the movement path, the one or more processors cause the vehicle control device to set a vehicle speed and a steering angle that enable a full steering axial force to be applied to the rack shaft within a range of being less than a maximum driving force which depends on the temperature of the steering motor.
