Problems solved by technology

[0004] The technical problem to be solved by the present invention is: when the existing electric vehicle goes downhill, the speed of the electric vehicle is often too fast due to the motor operation and the boost effect of the slope, which causes safety problems. People on the road will have the risk of people flying out due to inertia. The invention provides a safety brake circuit system for electric vehicles downhill that solves the above problems.

Description

technical field [0001] The invention relates to a control circuit, in particular to a downhill safety braking circuit system of an electric vehicle. Background technique [0002] At present, as a new type of transportation that saves energy and reduces emissions, electric vehicles are increasingly favored by people, and they bring convenience to people's travel. An electric vehicle is a vehicle that uses a battery as an energy source, and converts electrical energy into mechanical energy through controllers, motors and other components to control the current and change the speed. [0003] Existing electric vehicles often cause safety problems due to the motor running and the boosting effect of the slope when the electric vehicle is going downhill. Therefore, it is an urgent problem to be solved to take safety brakes when the electric vehicle goes downhill, so that the electric vehicle can achieve the purpose of deceleration and increase the safety of the downhill.
