Problems solved by technology

[0012] Therefore, when the internal combustion engine is stopped, if the control device supplies electric power from the battery to the steering motor of the electric power steering system, there is a possibility that the steering motor may not be able to generate an output of a desired value.
In addition, when the internal combustion engine is restarting, if the control device supplies electric power from the battery to the steering motor, there is a possibility that the steering motor may not be able to generate an output of a desired value.
[0013] Therefore, for example, if the control device stops or restarts the internal combustion engine by SS control while executing LKA control, there is a possibility that the steering angle of the steering wheel, which is changed by the steering motor, will be temporarily smaller than a desired angle.

Embodiment Construction

[0054] Below, refer to Figure 1 to Figure 9 , the vehicle 10 according to the embodiment of the present invention will be described.

[0055] First, based on figure 1 The overall structure of the vehicle 10 will be described.

[0056] Vehicle 10 includes a control device 50 . The control device 50 has an engine control ECU51, a vehicle control ECU52, a brake control ECU53, a camera control ECU54, a steering control ECU55, and a required voltage monitoring ECU56. ECU is the abbreviation of Electric Control Unit (Electronic Control Unit), which is equipped with a microcomputer including storage devices such as CPU, ROM, and RAM. The CPU executes instructions (programs) stored in the ROM to realize various functions. In addition, the engine control ECU51, the vehicle control ECU52, the brake control ECU53, the camera control ECU54, the steering control ECU55, and the required voltage monitoring ECU56 can mutually transmit and receive various control information and request s...

Abstract

A SS control device is configured to: be allowed to stop an internal combustion engine when a required voltage is smaller than or equal to a first voltage value under a state where a stopping condition is satisfied, and be prohibited from stopping the internal combustion engine when the required voltage is larger than the first voltage value under a state where the stopping condition is satisfied;and be allowed to restart the internal combustion engine when the required voltage is smaller than or equal to a second voltage value smaller than the first voltage value under a state where the restart condition is satisfied, and be prohibited from restarting the internal combustion engine when the required voltage is larger than the second voltage value under a state where the restart conditionis satisfied.

Description

technical field [0001] The present invention relates to a vehicle control device for controlling a vehicle equipped with an electric power steering device and capable of performing start and stop control. Background technique [0002] The vehicle disclosed in Patent Document 1 includes an electric power steering device. As is well known, a power steering device is connected to a steering wheel. In addition, the power steering device includes an electric steering motor. When electric power from a battery mounted on the vehicle is supplied to the steering motor, the output shaft of the steering motor rotates. An output shaft of the steering motor is connected to steered wheels of the vehicle via a transmission mechanism. Therefore, when electric power is supplied to the steering motor, the steering angle of the steered wheels of the vehicle and the steering angle of the steering wheel change. [0003] This vehicle-mounted control device can perform start-stop control (here...
