Controller for taking measures against abnormal shift upon starting motor-driven vehicle

摘要

When a traveling drive system is activated at a time t2 in response to a turning of an ignition switch to an ON state at a time t1, a request of P/N inhibit (a park lock release inhibit) from an electrically operated motor controller vanishes. Therefore, originally, according to an execution of a park lock release, the vehicle is started in response to a holding of a D position of a shifter. However, in a case where a park lock release inhibit state occurs at a time immediately before time t2 and the shifter is at the D position at time t2, a present shift inhibit flag takes over the park lock inhibit state at the time immediately before t2 until a time t3 at which the shifter returns to a home (H) position so that the above-described start of the vehicle is prevented.

主权项

1. A control apparatus for taking measures against a shift abnormality upon activation for an electrically driven vehicle equipped with a battery that is electrically connectable to and chargeable via an external power supply, startable via motive power from an electrically operated motor, and configured to travel in a traveling mode corresponding to a signal from a momentary shifter when, with a traveling drive system of the electrically driven vehicle activated, the momentary shifter is operated from a reference position, the control apparatus comprising:
a shift abnormality detecting device configured to detect whether the momentary shifter is kept at a position other than the reference position; and a traveling mode transfer inhibiting device configured to inhibit a transfer to the traveling mode corresponding to the position other than the reference position while the shift abnormality detecting device detects that the momentary shifter is kept at the position other than the reference position.
