An electrical energy steering module is greater than only a circuit board and connectors in an aluminum field. The module comprises the drivers, sign mills and MOSFET switches that energy and management the electrical motor. The module additionally comprises a present monitor circuit that measures the amps the motor is utilizing. The present monitor and different inputs to find out the temperature of the motor utilizing an algorithm that even elements within the ambient temperatures.
If the system detects a situation that would trigger the motor to overheat, the module will scale back the quantity of present going to the motor. The system may go right into a fail-safe mode, generate a DTC and alert the driving force with a warning mild or message.
Measuring the steering wheel place angle and fee of flip present essential info for electrical energy steering techniques. The scan device will usually show this info in levels. The steering angle sensor (SAS) is usually part of a sensor cluster within the steering column. The sensor cluster will all the time have multiple steering place sensor: Some sensor clusters have three sensors to substantiate the info. Some SAS clusters and sensor modules are related to a Controller Space Community (CAN) bus. The SAS module or cluster will be related on to the ABS/ESC module on a CAN bus, or it may be a part of the general CAN Community in a loop that connects numerous modules within the automobile.
The steering torque sensor measures the steering power utilized by the driving force and permits delicate management of the electrical steering help. It serves the identical perform as a spool valve in a hydraulic energy steering system.
