Abstract

A method for dynamic control of an electric vehicle operable based on a throttle value received from a throttle and a default throttle map correlating default output values with throttle values, the method including: determining a user parameter; detecting a condition indicative of perturbation; in response to detecting the condition indicative of perturbation, determining a replacement output value for a first throttle value based on the user parameter; and controlling vehicle operation to meet the replacement output value in response to receipt of the first throttle value.

Claims20

Dependent claims

A dynamic control method of an electric vehicle comprising:

selecting, via a processor, a first map of a plurality of maps of vehicle speed or throttle inputs to vehicle outputs;
receiving, at the processor, a vehicle speed or throttle input from an input device;
mapping, via the processor, the vehicle speed or throttle to a first power parameter based on the first map;
maintaining power, via the processor, to an electric motor of the electric vehicle within a range of the first power parameter;
detecting, via the processor and a sensor, a perturbation;
determining, via the processor, based on the perturbation, a second map of the plurality of maps of vehicle speed or throttle inputs to vehicle outputs;
mapping, via the processor, the vehicle speed or throttle input to a second power parameter based on the second map;
and
controlling power to the electric motor based on the second power parameter.

6 more elements

A method for dynamic control of an electric vehicle comprising:

achieving, via the electric vehicle, a first vehicle speed by application of a first manual driving force from the user;
determining, via a processor of the electric vehicle, the first vehicle speed based on a first sensor dataset sampled by a sensor associated with the electric vehicle during a first time period;
maintaining, via the vehicle, electric power during a second time period to drive the electric vehicle within a predetermined range of a first output vehicle speed selected based on the first vehicle speed;
achieving, via the vehicle, a second vehicle speed by application of a second manual driving force from the user;
determining, by the processor, the second vehicle speed based on a second sensor dataset sampled by the sensor during the second time period;
and
maintaining, via the vehicle, electric power provision during a third time period to drive the electric vehicle within a predetermined range of a second output vehicle speed selected based on the second vehicle speed.
