Vehicle control system

摘要

A vehicle control system includes: a power unit including an electric rotary machine; an electric coolant pump configured to circulate a coolant that cools the electric rotary machine; and a control unit configured to operate the electric coolant pump based on a condition that a temperature of the electric rotary machine is equal to or higher than a predetermined operation threshold temperature, and a condition that an output of the electric rotary machine is equal to or higher than a predetermined operation threshold output.

1. A vehicle control system comprising:
a power unit including an electric rotary machine; an electric coolant pump configured to circulate a coolant that cools the electric rotary machine, where a power supply of a driver circuit of the electric coolant pump is a low voltage power supply independent from the power supply unit of the electric rotary machine; and a control unit configured to operate the electric coolant pump based on a condition that a temperature of the electric rotary machine is equal to or higher than a predetermined operation threshold temperature, wherein the control unit is configured to operate the electric coolant pump additionally based on a condition that an output of the electric rotary machine is equal to or higher than a predetermined operation threshold output, wherein the output of the electric rotary machine relates to the output performance of the vehicle, wherein the control unit is configured to operate the electric coolant pump when the temperature of the electric rotary machine is equal to or higher than the predetermined operation threshold temperature and the output of the e electric rotary machine is equal to or higher than the predetermined operation threshold output, in a case where a vehicle drive mode is a first mode, and wherein the control unit is configured to operate the electric coolant pump when the temperature of the electric rotary machine is equal to or higher than the predetermined operation threshold temperature or the output of the electric rotary machine is equal to or higher than the predetermined operation threshold output, in a case where the vehicle drive mode is a second mode.
