Abstract
A start control system for a vehicle comprising: an electric motor brought into a starting state when an ignition key is operated to a starting position; an automatic transmission; and a shift unit having running ranges including drive, second speed, first speed and reverse ranges, and non-running ranges including parking and neutral ranges. Further comprised is a mechanism for allowing the shift unit to change the parking range to the drive range when the ignition key is operated to the starting position.
Claims16
A start control system for a vehicle comprising:
- an ignition key for outputting a starting signal when operated to a starting position;
- an automatic transmission
- a shift unit for changing said automatic transmission between a non-running range and a running range;
- a shift lock mechanism for selectively blocking the change from said non-running range to said running range
- an electric motor acting as a vehicular driving power source, wherein the automatic transmission is connected to an output side of the electric motor;
- start detecting means for detecting that said ignition key is operated to the starting position;
- and
- shift lock releasing means for releasing the block in the change of said shift unit from the non-running range to the running range by said shift lock mechanism, when the operation of said ignition key to the starting position is detected by said start detecting means.

A vehicle start control system which has:
- an electric motor for running the vehicle, an automatic transmission connected to the output side of said electric motor;
- a shift unit for changing said automatic transmission between a non-running range and a running range;
- and an ignition mechanism having an insertion position, for receiving an ignition key, a starting position for controlling said electric motor in a standby state, and an intermediate position between said insertion position and said starting position, comprising:
- electric motor control means for controlling said electric motor in the standby state when said ignition key is operated to said intermediate position and when said shift unit is changed to the running range.
