AFL control module (752)
| AFL control module (752) |
| Main task |
The AFL control module has the same functions as AHL control module (664) plus curve lighting.
When vehicle speed exceeds approx. 10 km/h the headlamps will be angled slightly when the steering wheel is turned. The light can be angled maximum 15° to the right or left compared to a car with standard headlamps.
The control system is equipped with two load angles sensors located at the front and rear axles. The system uses information from the steering angle sensor.
| Type |
The control module has a microprocessor with clock, RAM memory and a flashable ROM. An internal bus connects the processor and memories with the I/O unit. The I/O unit is responsible for loading the values from the A/D converter for analogue inputs, digital inputs on the bus and for activating the transistors in the power amplifiers.
