Abstract
An electrical switch assembly is provided for an electronically controlled transmission that allows user selection between a plurality of shift schedules for the transmission. The switch assembly provides a signal for selecting among the plurality of shift schedules and has a housing. A first set of electrical contacts are positioned within the housing, and selectively closable to cause the input signal to be indicative of a selection of a first shift schedule. A second set of electrical contacts are positioned within the housing and are selectively closable to cause input signal to be indicative of a selection of a second shift schedule.
Claims17
An electrical switch assembly for an electronically controlled transmission having a transmission controller arranged to provide a plurality of shift schedules for the transmission, the switch assembly providing an input signal to the transmission controller for selecting among the plurality of shift schedules, the switch assembly comprising:
- a housing;
- a first set of electrical contacts positioned within said housing, said first set of electrical contacts being selectively closable by operation of an input member to cause the input signal to be indicative of a selection of a first shift schedule;
- and
- a second set of electrical contacts positioned within said housing, said second set of electrical contacts being selectively closable by operation of the input member to cause the input signal to be indicative of a selection of a second shift schedule.
A system for a motor vehicle having an electronically controlled transmission for selecting among a plurality of shift schedules, the system comprising:
- a control module;
- an input switch connected to said control module, said input switch arranged to provide to the control module an input signal indicating the desired engagement status of said plurality of shift schedules;
- a transmission controlled by said control module, wherein said control module is arranged to cause the transmission to operate under a first shift schedule upon receipt of an input signal from said input switch indicative of the desired engagement of said first shift schedule, and to cause the transmission to operate under a second shift schedule upon receipt of an input signal from said input switch indicative of the desired engagement of said second shift schedule.
A method for selecting among a plurality of shift schedules for a motor vehicle having a transmission controlled by a transmission controller, the method comprising:
- monitoring a voltage level of an input signal and determining whether the operator has indicated a desired engagement of either a first shift schedule or a second shift schedule;
- disengaging said first shift schedule if the input signal is equal to a first voltage level;
- and
- engaging said second shift schedule if said input signal is equal to a second voltage level.
