摘要： An actuator control apparatus including a by-wire control circuit, a monitor circuit, a drive determination section, and a prohibition section is provided. The by-wire control circuit electrically controls an actuator acting as a drive source of an on-board apparatus. The monitor circuit monitors whether or not the by-wire control circuit is normally operating. The monitor circuit is provided separately from the by-wire control circuit. The drive determination section determines prohibition and permission of driving the actuator. The prohibition section prohibits the actuator from being driven when the permission of driving the actuator is not determined by the drive determination section. The prohibition section also prohibits the actuator from being driven when the monitor circuit determines that the by-wire control circuit is not normally operating.

摘要： An ECU determines whether or not there is an abnormality (shift pattern abnormality) in a combination of shift signals provided from a shift position sensor. After occurrence of the shift pattern abnormality is determined, ECU determines whether or not a first condition that a shift pattern has changed into a normal pattern of a drive range, a second condition that a brake is ON and a vehicle is in a stop state is satisfied, and a third condition that an accelerator is OFF are satisfied. When occurrence of the shift pattern abnormality is determined, ECU stops generation of driving force of the vehicle and prohibits switching to the drive range. When ECU determines that the above-mentioned first to third conditions are satisfied after occurrence of the shift pattern abnormality is determined, ECU switches the shift range to the drive range indicated by the shift pattern.

摘要： A transmission assembly for a vehicle includes a transmission and a controller. The transmission includes an input member, at least one clutch and gear set, and an output member. The input member receives an input torque from an engine. The output member receives an output torque from the clutch and gear set(s). The clutch and gear set(s) connect to the input member and establish a plurality of operating states including a neutral idle (NI) state. A designated NI clutch is selectively actuated to enter the NI state when the transmission is in a drive state and the vehicle is stationary. The controller calculates a reference slip error as a function of engine and turbine speed, and detects when the designated NI clutch is exhausting fluid while operating in the NI state using a function of the reference slip error. A control action executes when the exhausting NI clutch is detected.

摘要： A clutch actuator and to a method for the control thereof. The actuator actuates a multi-disk clutch, and to do so has actuator modules. The number of which corresponds to the number of the friction clutches. The modules have separate control units and electric motors, which are controlled by the control units and act on the friction clutches by a disengaging mechanism. In order to counter block the partial drive trains disposed downstream of the friction clutches, particularly automatically closed friction clutches during a malfunction of an actuator module, the actuator modules are connected among each other to a data line, which allows monitoring of the actuator modules and counter-measures.
