What does autoh mean on a car?

Autoh on a car refers to the Auto Hold system. The application of the Auto Hold function technology allows drivers to avoid unnecessary vehicle sliding without the need for prolonged braking or activating the electronic parking brake. Additionally, this function prevents the vehicle from rolling backward when starting on a slope. When using Auto Hold, simply press the button lightly to activate the corresponding automatic parking function. The Auto Hold function enables the vehicle to automatically engage four-wheel braking when stopping at traffic lights or on slopes, even in D or N gear, eliminating the need to continuously press the brake pedal or use the handbrake. The vehicle remains stationary, and to release the stationary state, simply lightly press the accelerator pedal to disengage the brake.
As a seasoned driver with years of experience, I believe Autoh usually refers to the Auto Hold function, which means automatic brake hold. When you come to a complete stop, the system automatically applies braking force, eliminating the need to keep your foot on the brake pedal; a light tap on the accelerator releases it when restarting. This is especially useful during city red lights or traffic jams, sparing me the effort of maintaining brake pressure and preventing increased fatigue. On some slopes, it also prevents rolling back, enhancing safety. Although it sounds high-tech, the principle is quite simple—the vehicle's electronic stability system and sensors detect the stopped state to operate automatically. I often drive long distances or in heavy traffic, and this feature makes driving much more relaxed. Nowadays, most new cars come equipped with this, and I recommend trying it once—you won't want to go back.
From a technical perspective, Autoh is the abbreviation for Auto Hold, which is essentially an automatic brake hold system. When the vehicle comes to a complete stop, sensors trigger the electronic brake to apply pressure, effectively holding the brake pedal for you; pressing the accelerator while driving releases it. This system is integrated into the vehicle stability program and is typically used in conjunction with auto start-stop to reduce operational burden. Compared to traditional handbrakes, it reacts quickly without delay and is more reliable on slopes. I've seen the internal mechanism at auto shows—some vehicles even allow customization of sensitivity. In terms of energy efficiency and environmental protection, it avoids unnecessary foot brake operations, saving fuel over time. Overall, this feature in modern vehicles enhances convenience and efficiency.
From a safety perspective, Autoh automatically engages the brakes when parking, effectively preventing vehicle rollback. Especially for novice drivers or in busy streets, it reduces the risk of rear-end collisions. I've experienced several instances where I didn't press the brake properly at a red light and almost hit the car in front—this feature eliminates such hazards. It also provides stable support when parking on slopes or in tunnels. After using auto hold, driving becomes more focused on road condition control rather than being distracted by pedal operation.
