Is it necessary to shift to N gear when using auto hold?
1 Answers
Whether to shift to N gear when using auto hold depends on the specific situation: 1. If the parking time is short, it is not necessary to shift to N gear; 2. If the parking time is long, it is necessary to shift to N gear. Auto hold refers to an automatic braking function. After activating this function, it can simplify operations by avoiding the use of handbrakes or electronic handbrakes. For automatic transmission models, there is no need to frequently switch between D to N or D to P. The function of auto hold is to prevent the vehicle from rolling, which is suitable for uphill, downhill, or frequent starts and stops. The working principle of auto hold is: the controller provides accurate parking force through the slope sensor. When starting, the parking control unit calculates the information provided by the clutch distance sensor, clutch engagement speed sensor, and accelerator pedal sensor. When the driving force is greater than the driving resistance, the parking brake is automatically released, allowing the car to start smoothly.
