Throttle pedal control method for converting CAN data to analog quantity data based on gateway and DA module

The invention discloses a throttle pedal control method for converting CAN data to analog quantity data based on a gateway and a DA module. The throttle pedal control method comprises the steps that an upper computer in a car with throttle pedal position signals being 0.75V-3.75V and 0.375V-1.875V two-way voltage analog quantity signals analyzes a VCU communication protocol, data information can be converted through the gateway, analog quantity is converted to digital quantity, the upper computer sends digital quantity information to the gateway according to the conversion relationship betweenthe analog quantity and the digital quantity, after the gateway analyzes the data information, the data information is converted to the analog quantity through the DA module, the analog quantity is sent to a VCU, and thus control over a throttle is achieved. According to the throttle pedal control method, the problem that when an intelligent driving car is switched to be in a manual mode or an automatic driving mode, the
