Abstract: A start control apparatus includes a position sensor, a basic start determination processor, a sensor output determination processor, and a start permission continuation processor. The basic start determination processor determines whether a sensor output is in a permission region for permitting the start of operation of a motor when an engine start range is selected, and generates a start permission signal when the sensor output is in the permission region. The sensor output determination processor determines whether distinctive variation characteristics are detected in the sensor output when the motor is started based on the start permission signal and supply of electrical current to the motor. The start permission continuation processor permits continuation of operation of the motor when the variation characteristics are detected.

Abstract: A sensor generates a continuous signal in response to operation of a shift lever, and a range is determined for each of the various control operations by comparing the output value of the signal with a range determination pattern set arbitrarily for each of the control operations. Accordingly, each of the control operations can be performed appropriately by using optimal range information.

Abstract: A shift control apparatus for an automatic transmission eliminates or reduces a sense of discomfort to the driver and other occupants during slip, while maintaining the necessary driving force. When slip is determined by detection of wheel speed, a slip signal is output. A controller which receives the slip signal outputs a maintaining signal for maintaining the gear stage which existed at the time the slip signal was received, until a predetermined period of time has passed. If the slip continues after the predetermined period of time, the controller outputs a shift signal to the automatic transmission to shift it to a predetermined gear stage, thus reducing driving force and preventing slip from continuing. If the slip stops within the predetermined period of time, the slip signal is canceled such that the current gear stage is maintained and no shift is executed.

Abstract: A shift control apparatus for an automatic transmission is provided in which, during slip, a sense of discomfort to the driver and other occupants is eliminated or reduced and the necessary driving force is obtained. When slip is detected by detecting the speed of the wheels by wheel speed detecting means, slip determining means outputs a slip signal. Maintaining means into which the slip signal has been input then outputs to shifting means a maintaining signal for maintaining the gear stage (for example, first speed) at the point during which the slip signal was input until a predetermined period of time has passed. If slip continues after the predetermined period of time has passed, the shifting means outputs a shift signal to the automatic transmission to shift it to a predetermined gear stage (for example, third speed), thus reducing driving force and preventing slip from continuing.
