TWO STEP SMART KEY START SYSTEM
An ignition start system in which authentication of a key is carried out twice, first to activate the ignition switch to allow starting the engine and second at the time prior to moving the vehicle from a parked position. The two step authentication prevents driving off in a car that has been started without having the key for security purposes and also to avoid inconvenient situations that can otherwise occur.
1 . A vehicle, comprising:
a controller comprising a processor configured to authenticate a code; and
a vehicle movement activator,
wherein the processor is configured to perform a first code authentication when the vehicle is started enabling movement of the vehicle out of a park position and a second code authentication enabling movement of the vehicle out of a park position after the vehicle movement activator was previously moved from a drive position to a park position after starting the vehicle.
2 . The vehicle of claim 1 , wherein the first code authentication comprises detection of a mobile device within a passenger compartment of the vehicle.
3 . The vehicle of claim 1 , wherein the second code authentication comprises detection of a mobile device within a passenger compartment of the vehicle.
4 . The vehicle of claim 1 , wherein the second code authentication comprises detection of a mobile device within a passenger compartment of the vehicle when a person is within the passenger compartment of the vehicle.
5 . The vehicle of claim 1 , wherein the code authenticated for the first code authentication is the same as the code authenticated for the second code authentication.
6 . The vehicle of claim 1 , wherein the code authenticated for the first code authentication differs from the code authenticated for the second authentication.
7 . The vehicle of claim 4 , wherein the mobile device communicates wirelessly with a controller.
8 . The vehicle of claim 1 , wherein the controller prevents operation of a vehicle movement activator when a brake system is activated with the vehicle started in the absence of the second code authentication.
9 . The vehicle of claim 1 , wherein the vehicle movement activator is inoperable after starting the vehicle and deactivation of a brake system to prevent movement of the vehicle after the vehicle is initially started and the brake system is activated by a user without a mobile device being detected in a vehicle passenger compartment after starting the vehicle.
