The throttle control apparatus includes a throttle opening degree sensor for detecting the degree of opening of the throttle valve. An engine operating condition detecting device is operative to detect an operating condition of the engine. A throttle opening degree estimating device is operative to estimate the degree of opening of the throttle valve on the basis of the operating condition of the engine which is detected by the engine operating condition detecting device. A memorizing means serves to memorize a corrective quantity. A corrective quantity updating device is operative to update the corrective quantity memorized by the memorizing device on the basis of a difference between an output value from the throttle opening degree sensor and an estimated value from the throttle opening degree estimating device. A control device serves to adjust a controlled quantity of the actuator in response to the output value from the throttle opening degree sensor and the corrective quantity memorized by the memorizing device to control the degree of opening of the throttle valve.

摘要： A vehicle slip control system for controlling a wheel slip based on a friction coefficient of a road surface measures an engine torque T.sub.E by applying an intake pipe negative pressure Pm and a number of engine revolutions Ne to an engine model. A drive torque T is measured by applying the engine torque T.sub.E to an A/T model, and a driving wheel acceleration d.omega. is obtained by finding a difference of a detected driving wheel speed .omega.. By filtering this driving wheel acceleration d.omega., a post-filter driving wheel acceleration d.omega..sub.0 is calculated. A squat force Ws is calculated from the drive-torque T and the post-filter driving wheel acceleration d.omega., and a friction coefficient .mu. of the road surface is estimated from the squat force Ws. The estimated friction coefficient .mu. is used to control a wheel slip.

摘要： A motor controlling device includes an encoder to output pulse signals with a predetermined angle interval as a rotor of a motor is rotated. An energized phase of the motor is sequentially switched by detecting a rotation position of the rotor based on a value of counting the signals. An initial drive controlling portion executes an initial drive to switch the energized phase with a predetermined pattern after the device is activated so as to learn a relationship among the count value, the rotation position and the energized phase. An initial drive prohibiting portion prohibits the execution of the initial drive until a predetermined time is elapsed after the initial drive is finished.

摘要： A control apparatus for a range changeover device checks whether an actual range agrees with a target range. If the actual range differs from the target range, the control apparatus performs vehicle driving force restriction control irrespective of a presence/absence of abnormality in a range changeover operation. The control apparatus may restrict an engine output power by closing a throttle valve of the engine to around an idle position, thereby restricting the vehicle driving force.

摘要： A motor needs to provide a first torque at the time of releasing a shift range from a parking range and needs to provide a second torque smaller than the first torque at the time of placing the shift range into the parking range. Also, the motor needs to provide a third torque smaller than the second torque at the time of changing the shift range from one non-parking range to another non-parking range and needs to provide a fourth torque smaller than the third torque at the time of executing the parking range wall abutment learning. When the parking range wall abutment learning is executed from the parking range, a motor control apparatus controls the torque to the third or fourth torque. When the parking range wall abutment learning is executed from any non-parking range, the motor control apparatus controls the torque to the first or second torque.

摘要： A P-range side delimiting position of a movable range of a range change mechanism is learned by rotating a motor to a corresponding rotational position, which corresponds to the P-range side delimiting position. A climb correction amount is set for a learning value of the P-range side delimiting position to correct the learning value of the P-range side delimiting position in view of presence of a relatively small angle of rotation of the motor beyond the corresponding rotational position, which corresponds to the P-range side delimiting position. The climb correction amount is set according to motor temperature information, which is one of a temperature of the motor and a temperature that relates to the temperature of the motor.
