Keyless engine controlling unit
First Claim
Patent Images
1. A keyless engine controlling unit for controlling an engine of an automotive vehicle, comprising:
- an ignition switch for generating starting and stopping instructions of said engine by inserting and operating a key thereinto;
a door lock for locking an opening/closing mechanism such as a door; and
an automatic transmission;
said controlling unit further comprises;
a locked state detecting mechanism for detecting a state of a door lock switch for operating said door lock;
a selected state detecting mechanism for detecting a select lever state of said automatic transmission; and
an engine drive controlling mechanism for bypassing a contact point of said ignition switch,wherein, when said engine is in a running state, said selected state detecting mechanism detects that said select lever is positioned in park, said door lock switch of a door on a driver'"'"'s seat side is turned on and off by a predetermined number of operations, said contact point of said ignition switch is bypassed, thus maintaining said running state of said engine even when said key is extracted from said ignition switch.

Abstract
A keyless engine controlling unit has a set switch for setting an engine in a running state, a selected state detecting mechanism for detecting the position of a select lever of an automatic transmission, and an engine drive controlling mechanism for bypassing a contact point of an ignition switch. During engine operation, the selected state detecting mechanism detects that the select lever is in park, the set switch is set, and the contact point of the ignition switch is bypassed. Thus, the engine is maintained in the running state even if the key is extracted from the ignition switch.
