Does Auto Hold Increase Fuel Consumption?

[McCamilla]

Auto Hold systems do not cause an increase in a car's fuel consumption; this system is unrelated to the vehicle's fuel usage. Many cars are equipped with Auto Hold systems, and some models also feature an engine start-stop system alongside Auto Hold, making the two systems very convenient when used together. Additional Information: 1. Auto Hold refers to an automatic braking function. Once activated, it eliminates the need to use the handbrake, simplifying operations by avoiding manual or electronic handbrake use. For automatic transmission models, it also reduces the need for frequent shifting between D to N or D to P. 2. Traditional handbrakes require the driver to manually release the brake or skillfully coordinate the throttle and clutch for a smooth start on slopes. In contrast, the Auto Hold function uses a slope sensor to provide precise braking force via the control unit. During startup, the parking control unit calculates data from sensors such as clutch distance, clutch engagement speed, and throttle pedal position. When the driving force exceeds the rolling resistance, the system automatically releases the parking brake, ensuring a smooth and effortless start.
