What does the 'set' indicator on the car mean?

The 'set' indicator on the car refers to the cruise speed control switch. When you want to set the cruise speed, accelerate the car to the desired speed and press the 'set' button. At this time, the car speed usually needs to be greater than 30 miles per hour. If you step on the brake while using cruise speed control, the cruise speed control will stop working. The 'set' system mainly consists of a command switch, sensors, ECU, and an actuator. The ECU has two input signals: one is the command speed signal set by the driver as required, and the other is the feedback signal of the actual driving speed. After the controller detects the error between these two input signals, it generates a throttle control signal sent to the throttle actuator, so that the throttle actuator adjusts the opening of the engine throttle according to the throttle control signal to correct the error detected by the electronic control device and keep the speed constant.
