what does avh mean in a car

AVH stands for "Auto Vehicle Hold." It is a feature often found in modern vehicles, particularly in automatic transmission cars. The purpose of AVH is to improve convenience and safety during stops, such as at traffic lights or in stop-and-go traffic. Here are some details about how it works and what it does:

Functionality of AVH:

  1. Automatic Brake Hold: When the vehicle comes to a complete stop, the AVH system automatically engages the brakes and holds the vehicle in place without the driver needing to keep their foot on the brake pedal.

  2. Activation: To use the AVH feature, the driver typically needs to activate it, often through a button marked "AVH" or "Auto Hold" on the dashboard. Some vehicles may enable it automatically when the driver comes to a stop.

  3. Release of the System: The brakes will remain applied until the driver accelerates, at which point the AVH system releases the brakes automatically, allowing the vehicle to move forward smoothly.

  4. Convenience: This feature eliminates the need to hold the brake pedal during long stops, enhancing driver comfort and reducing fatigue, especially in heavy traffic conditions.

  5. Enhanced Safety: By preventing the vehicle from rolling back on inclines and ensuring it stays stationary without constant foot pressure, AVH contributes to overall road safety.

  6. Integration with Other Systems: AVH may work in conjunction with other driving assist systems, such as adaptive cruise control and hill-start assist, to provide a more seamless driving experience.

Importance:

  • Driver Comfort: Reduces stress and strain on the driver, especially in slow or congested traffic.
  • Safety: Increases safety by helping prevent unintended movements of the vehicle when stopped.

In summary, AVH (Auto Vehicle Hold) is a useful feature that enhances convenience and safety for drivers by allowing them to take their foot off the brake while the vehicle is stationary, automatically holding it in place until they’re ready to move again.
