CONTROL SYSTEM OF VEHICLE
First Claim
1. A control system installed on a vehicle having an electric motor as a drive power source, comprising:
- an electronic control unit configured to switch the vehicle between an automatic driving mode using automatic drive control, and a manual driving mode in which the vehicle is operated by a driver, the electronic control unit being configured to limit a load factor of the electric motor, in a case where a temperature of the electric motor is higher than a first threshold temperature when the vehicle travels in the automatic driving mode, and a case where the temperature of the electric motor is higher than a second threshold temperature when the vehicle travels in the manual driving mode, the second threshold temperature being set to a value that is higher than the first threshold temperature.

Abstract
A control system is installed on a vehicle having an electric motor as a drive power source. The control system includes an electronic control unit configured to switch the vehicle between an automatic driving mode using automatic drive control, and a manual driving mode in which the vehicle is operated by a driver. The electronic control unit is configured to limit the load factor of the electric motor, in the case where the temperature of the electric motor is higher than a first threshold temperature when the vehicle travels in the automatic driving mode, and the case where the temperature of the electric motor is higher than a second threshold temperature when the vehicle travels in the manual driving mode. The second threshold temperature is set to a value higher than the first threshold temperature.
