Claims

[Scope of Claim for Utility Model Registration] 1. An electric vehicle that is equipped with an abnormality detection circuit and a brake control circuit that operates a brake of a wheel drive motor by an abnormality signal from the abnormality detection circuit, and The vehicle is equipped with a switch capable of generating the above-mentioned abnormality signal, so that when a person gets on or off the electric vehicle, the switch is used to force the vehicle to stop in an abnormal state so that the person can get on or off the electric vehicle safely. Electric car. 2"--The abnormality detection circuit detects whether the sliding terminal voltage of the variable resistor that controls the speed of the wheel drive motor based on the sliding terminal voltage change is below the lower limit setting value or above the upper limit setting value, and detects an abnormality. Claim 1, which is a circuit that outputs a signal
Electric vehicles mentioned in section.
