Dynamic Apply
There are two 'Dynamic Apply' modes; low speed dynamic and high speed dynamic. The low speed dynamic mode operates at speeds between 2 mph (3 km/h) and 20 mph (32 km/h). The high speed dynamic mode operates at speeds above 20 mph (32 km/h)
If the parking brake switch is pulled up to the 'Apply' position and vehicle speed is within the low speed dynamic range, the control module drives the actuator to apply full parking brake force to the rear wheels.
If the parking brake switch is pulled up to the 'Apply' position and vehicle speed is within the high speed dynamic range, the control module will apply braking force to the rear wheels at a slower rate until full braking load is reached or the switch is released. The rate with which braking force is applied is controlled by the control module, which monitors both current drawn by the actuator and positional information from the actuator hall sensor and compares this to information held within its configuration software.
