110 water temperature detecting units are used to the temperature detecting circulating water, this unit is outside to be connected with the cooling-water temperature sensor of retarder body, AC/DC converting unit that is inner and MCU is connected, the effect of this circulating water is the temperature for cooling retarder, when water temperature reduces by one grade of work higher than retarder during setting value, if water temperature still can reduce moment gradually higher than setting value retarder, until temperature is lower than setting value.
120 oil temperature detecting units are the temperature for detecting retarder intracavity liquid oil, this unit is outside to be connected with the oil temperature sensor of retarder body, the AC/DC converting unit temperature be connected as oily in fruit caving that is inner and MCU can reduce by one grade higher than setting value retarder and work, if oil temperature still can reduce moment gradually higher than setting value retarder, until temperature is lower than setting value.
130ABS/ throttle detecting unit is that this unit is connected with the ABS signal in car and throttle signal end respectively, if in running order, retarder forbids work, otherwise retarder is in readiness for action for detecting ABS or whether throttle is in running order.
140 Bus-Speed Monitoring unit are for detecting the speed of automobile current driving, and this unit is outside to be connected with the C3 signal in gauge panel, and inside is connected with the input capture unit of MCU; Controller detects the speed of running car constantly by this unit, adjusts the pressure in retarder epitrochoidal chamber according to the velocity amplitude before shelves, and then the output torque of adjustment retarder.
The effect of 150 proportional valve control unit controls the pressure in epitrochoidal chamber, by controlling the aperture of the size control ratio valve of outgoing current thus the suction quantity controlled in epitrochoidal chamber reaches the object controlling pressure.This unit is outside to be connected with apportioning valve, and PWM output unit that is inner and MCU is connected, and controls the size of outgoing current according to the dutycycle size of the pwm signal of MCU output.
160 pressure signal detecting units are for detecting the pressure in retarder cavity, and this unit is outside to be connected with the pressure sensor on retarder body, and AC/DC converting unit that is inner and MCU is connected.
170 serial communication unit are used for the data interaction of controller and upper computer, by the information transmission in controller to upper computer, some values of information when level controller detects are demonstrated in upper computer, the parameter that will arrange is transferred to the parameter of controller change control device inside by upper computer, the outside inside that is connected with upper computer of this unit is connected with the SCI module of MCU simultaneously;
180 stoplight stop lamp control units are used for the control to stoplight stop lamp, and when retarder works, stoplight stop lamp is in bright state, otherwise stoplight stop lamp is in the state of going out, and this unit outside is connected with stoplight stop lamp control signal, and inside is connected to the control unit of MCU.
This part of 190 gear position detecting unit is arranged for the gear of retarder, retarder can be divided into 6 gears, 0 grade (does not produce moment, retarder quits work), 1 grade (constant speed shelves), 2 grades the moment of 25% (produce), 3 grades (producing the moment of 50%), 4 grades (producing the moment of 75%), 5 grades (producing the moment of 100%), this unit outside is connected with arm cook or Foot-controlled switch, and inside is connected with the detecting unit of MCU.
