Description

Electric vehicle safety operation control device

This creation is related to a safe operation control, especially an electric vehicle safety operation control device.

Some vehicles in the automotive field use pneumatic brakes, hydraulic brakes or composite brakes that use air pressure combined with oil pressure. However, the life of a vehicle can often reach several decades, and the related parts of a vehicle often only last for several years. Life expectancy, if the car is not repaired or negligent, it may cause serious damage to the driver, passengers and surrounding vehicles due to the old parts, so the user's willingness to install the pressure detector is greatly increased, and it can be used during maintenance. The pressure of the brake device is checked. Although the installation of a pressure detector or other sensor can improve the convenience of inspection, it still cannot be positioned as an active safety device.

Due to the arrival of middle-aged society, driving may be caused by unintentional operation errors due to high age, busy life or mental retardation. For example, before the vehicle is turned on, the gearshift lever is operated forward. If the gear position or the reverse gear position is turned on, the vehicle will be powered on, causing the vehicle to burst into violent motion, or the vehicle may fail to brake the vehicle and the child may accidentally step on the accelerator door to stop the vehicle. It may be possible to treat people, things, things and the environment around. Cause damage.

With the advancement of technology and the rise of environmental awareness, the number of people using electric vehicles has gradually increased. Among them, the circuit system of the general commercial vehicle is complicated, and the battery of the electric vehicle is expensive and the life is not good, and the battery life of the electric vehicle is often degraded due to the interaction of the vehicle circuit. Nowadays, the safety awareness of the society is improved.
