Hill Start Assistance
Assisting starting off on a slope
This technology allows drivers to change pedals easily from the brake to the accelerator and carry out a safer hill start.
Technology Functionality
When a driver changes pedals from the brake to the accelerator in order to start the car on a slope, the system maintains the brake pressure for a maximum of two seconds after the driver’s foot has left the brake pedal. By keeping the car at a standstill even when not pressing down on the brake, the system helps to prevent against rolling backwards when starting off on a slope.
Technology Configuration
An acceleration sensor using VDC (vehicle dynamic control) detects when the vehicle is on a slope. It does not engage at a place that seems close to a flat road. When a slope is detected by the acceleration sensor, the brake pressure applied by the driver stepping on the brake pedal is maintained for a maximum of two seconds after the driver releases their foot. When the driver operates the accelerator, the brake pressure is unlocked.
