SPEED LIMIT
FUNCTION OF SPEED LIMIT
- Speed Limit Programming: The speed limit is programmed into the vehicle's ECU software. This limit is determined during the production phase or can be updated later at authorized services.
- Speed Sensors: Speed sensors in the vehicle constantly report the instantaneous speed of the vehicle to the ECU. These sensors can often be wheel speed sensors or transmission output speed sensors.
- ECU Control: The ECU constantly monitors data from speed sensors. When the vehicle speed approaches or exceeds the set speed limit, the ECU controls the vehicle's speed by various methods, such as limiting engine power or reducing fuel supply.
- Warnings and Interventions: When the speed limit is approached, some vehicles give warning signals to the driver (for example, a light on the instrument panel or an audible warning). If the speed limit is exceeded, the ECU prevents the speed from increasing by throttling the engine or reducing the fuel supply.
PROBLEMS OF SPEED LIMIT
- The speed is limited to a certain KM/H. And you cannot exceed this speed limit.
