Abstract
Disclosed herein a method for upshifting the transmission of a vehicle using shift entry prediction. The method may comprise predicting whether or not an upshift request of a vehicle will occur, determining whether or not a charge demand required for a battery through regeneration for upshift is greater than an allowable charge amount of the battery when the upshift request is predicted, controlling power consumption of the battery when the charge demand is greater than the allowable charge amount, and processing the upshift in response to an actual request of the upshift.
Claims18
A method of operating a vehicle, comprising:
- predicting whether the vehicle will receive a request for an upshift;
- determining whether an amount of regenerative charge that will be produced based on the upshift satisfies an amount of allowable charge that can be transferred to a battery, of the vehicle, at a time point when the vehicle is predicted to receive the request for the upshift;
- controlling, based on the amount of regenerative charge satisfying the amount of allowable charge, power consumption of the battery;
- after receiving the request for the upshift, processing the upshift;
- predicting that the vehicle will not receive a request for a second upshift based on a condition that:
- a second shift speed, associated with the second upshift, does not exist between a requested constant speed and a current speed of the vehicle;
- and
- the second shift speed is higher than the requested constant speed;
- determining whether an amount of second regenerative charge associated with the second shift speed is greater than the amount of allowable charge;
- and
- controlling, based on the amount of second regenerative charge being greater than the amount of allowable charge, second power consumption of the battery.
A vehicle comprising:
- a battery;
- at least one motor configured to generate a driving force of the vehicle based on receiving power from the battery;
- a transmission configured to shift the driving force;
- and
- a processor configured to:
- predict whether the transmission will receive a request for an upshift;
- determine whether an amount of regenerative charge that will be produced, by the at least one motor, based on the upshift satisfies an amount of allowable charge that can be transferred to the battery at a time point when the transmission is predicted to receive the request for the upshift;
- control, based on the amount of regenerative charge satisfying the amount of allowable charge, power consumption of the battery;
- after receiving the request for the upshift, process the upshift by controlling the at least one motor and the transmission;
- predict that the transmission will not receive a request for a second upshift based on a condition that:
- a second shift speed, associated with the second upshift, does not exist between a requested constant speed and a current speed of the vehicle;
- and
- the second shift speed is higher than the requested constant speed;
- determine whether an amount of second regenerative charge associated with the second shift speed is greater than the amount of allowable charge;
- and
- control, based on the amount of second regenerative charge being greater than the amount of allowable charge, second power consumption of the battery.
A vehicle comprising:
- a battery;
- at least one motor configured to generate a driving force of the vehicle based on receiving power from the battery;
- a transmission configured to receive the driving force;
- a processor;
- and
- a memory storing at least one instruction, wherein the at least one instruction, executed by the processor, is configured to cause the vehicle to:
- determine a predicted upshift of the transmission;
- determine whether an amount of regenerative charge that will be produced, by the at least one motor, based on the predicted upshift is greater than an amount of allowable charge that can be transferred to the battery;
- control, based on the amount of regenerative charge being greater than the amount of allowable charge, power consumption of the battery;
- after receiving a request for an upshift, process the upshift by controlling the at least one motor and the transmission;
- and
- predict that a request for a second upshift associated with the transmission is not expected based on a condition that:
- a second shift speed, associated with the second upshift, does not exist between a requested constant speed and a current speed of the vehicle;
- and
- the second shift speed is higher than the requested constant speed.
