Abstract

The present invention provides a vehicle and a vehicle control method. In the present invention, a vehicle (100) comprises the following: a motor generator (130) for outputting power for running; a PCU (120) for driving the motor generator (130); and an ECU (300) for controlling the PCU (120). The ECU (300) detects a state in which drive wheels (150) of the vehicle (100) are to surmount a grade difference on the road. In response to detection of the state in which a grade difference is to be surmounted, the ECU (300) controls the PCU (120) so as to restrict the upper limit value of the running speed of the vehicle (100) to a value that is lower than that when the state in which grade difference is to be surmounted is not detected.

Description

technical field [0001] The present invention relates to a vehicle and a control method of the vehicle, and particularly relates to drive control of a vehicle capable of traveling by driving force from a rotating electric machine. Background technique [0002] In recent years, vehicles equipped with power storage devices (for example, secondary batteries, capacitors, etc.) and driven by driving force generated from electric power stored in the power storage devices have attracted attention as environmentally friendly vehicles. The vehicle includes, for example, an electric vehicle, a hybrid vehicle, a fuel cell vehicle, and the like. [0003] In these vehicles, an inverter is generally used to convert DC power from a power storage device into AC power for driving a rotating electric machine such as a motor generator. Then, the vehicle is driven using the driving force generated by the rotary electric machine, and during regenerative braking, etc., the rotational force from t...
