Keyless control system
First Claim
1. A keyless control system for a vehicle, comprising:
- an actuator mounted on the vehicle and movable between first and second positions;
a switch coupled to the actuator, the switch assuming a first state when the actuator is in the first position and a second state when the actuator is in the second position, wherein the switch is a two-position switch that includes only two operable positions, and wherein a first one of the two operable positions corresponds to the first state and a second one of the two operable positions corresponds to the second state;
a display disposed in a cabin of the vehicle; and
a controller coupled to the switch and the display and configured to;
detect a first actuation sequence of the actuator as a succession of changes in state of the switch resulting from corresponding successive movements of the actuator between the first and second positions, the first actuation sequence corresponding to an access code, wherein the first actuation sequence is used to convey a plurality of digits comprising the access code, wherein for each of the plurality of digits of the access code, the number of successive movements of the actuator between the first and second positions is equal in number to the digit being conveyed, and pauses during the successive movements of the actuator that are longer in duration than a threshold time period identify transitions between each of the plurality of digits during the conveyance of the digits;
compare the access code to a predetermined authorization code saved to a memory accessible by the controller;
generate a first control signal configured to allow access to an interior compartment of the vehicle or to cause starting of the vehicle when the access code corresponds to the predetermined authorization code; and
control the display to display characters associated with each digit of the access code that provides visual validation during entry of the first actuation sequence.

Abstract
A keyless entry and start system for a vehicle includes a vehicle subsystem configured to control at least one of access to an interior compartment of the vehicle and starting of the vehicle. The system further includes an actuator movable between first and second positions and a switch coupled to the actuator. The switch assumes a first state when the actuator is in the first position and a second state when the actuator is in the second position. The system further includes a controller coupled to the switch and configured to detect an actuation sequence of the actuator, the actuation sequence corresponding to an access code. The controller is further configured to compare the access code to an authorization code and generate a control signal configured to cause the vehicle subsystem to switch states when the entry code corresponds to the authorization code.

9. A keyless control system for a vehicle, comprising:
-
an actuator mounted on the vehicle and movable between first and second positions; a switch coupled to the actuator, the switch assuming a first state when the actuator is in the first position and a second state when the actuator is in the second position, wherein the switch is a two-position switch that includes only two operable positions, and wherein a first one of the two operable positions corresponds to the first state and a second one of the two operable positions corresponds to the second state; a display disposed in a cabin of the vehicle; and a controller coupled to the switch and the display and configured to; determine whether an initial actuation sequence of the actuator, defined by successive movements of the actuator between the first state and the second state, corresponds to a predetermined activation sequence saved to a memory accessible by the controller by; when the initial actuation sequence of the actuator does not correspond to the predetermined activation sequence, after a first predetermined amount of time, clear the initial actuation sequence of the actuator so as to allow a user to re-attempt matching the predetermined activation sequence; and once the initial actuation sequence of the actuator corresponds to the predetermined activation sequence transmit an output signals to the display, the output signals configured to cause the display to display a single character of a set of characters for a second predetermined amount of time, after the second predetermined amount of time, carry out the transmitting action for a different character of the set of characters so that the different character is displayed as the single character on the display for the second predetermined amount of time, detect actuation of the actuator during the second predetermined amount of time for any given single character on the display, wherein the single character currently displayed at the time of actuation of the actuator is stored as an entered character of a first actuation sequence, repeat the transmitting, carrying out, detection, and storing actions at least until a determination can be made as to whether the sequence of entered characters in the first actuation sequence matches a sequence of characters in a predetermined authorization code saved to a memory accessible by the controller, when the determination is made that the first actuation sequence does not correspond to the predetermined authorization code, clear the first actuation sequence so as to allow a user to re-attempt matching the predetermined authorization code, and increment a counter, when the counter is incremented to a threshold count value, cause the display to either turn off or to present a visual alert to the user of a failed attempt to correctly enter the predetermined authorization code, generate a first control signal configured to allow access to an interior compartment of the vehicle or to cause starting of the vehicle when the first actuation sequence corresponds to the predetermined authorization code, and reset the counter. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
