Abstract
Disclosed is a method for controlling the speed of a vehicle, the method comprising: determining a speed limit; determining an offset value based on (i) the speed limit, and (ii) a speed map, the speed map comprising a plurality of entries, each entry associating one of the offset values with a respective speed limit; and setting the speed of the vehicle according to the speed limit and the determined offset value.
Claims17
A method for automatically controlling a speed of a vehicle, the method comprising:
- receiving a first user input to initiate speed control from a driver and initiating speed control;
- retrieving a speed map associated with the driver, wherein the speed map is generated using geographic speed limits and learned driver behaviors, the speed map comprising a plurality of entries, each entry comprising a speed limit and an offset value, wherein the offset value is determined by driver-defined offset values and the learned driver behaviors;
- determining the speed map does not contain a first entry associated with a first location of the driver;
- interpolating using the plurality of the entries in the speed map and generating the first entry;
- recording a current speed limit and a new offset value determined by the driver-defined offset values and the learned driver behaviors pursuant to a second user input;
- revising the first entry to include the current speed limit and the new offset value;
- and
- automatically setting the speed of the vehicle according to the new offset value upon subsequent operation of the vehicle at the recorded current speed limit.
A method for automatically controlling a speed of a vehicle, the method comprising:
- receiving a first user input to initiate speed control from a driver and initiating speed control;
- determining a presence of an adverse-condition;
- retrieving a speed map associated with the driver, wherein the speed map is generated using geographic speed limits and learned driver behaviors, the speed map comprising a plurality of entries, each entry comprising a speed limit and an offset value, wherein the offset value is determined by driver-defined offset values and the learned driver behaviors;
- determining the speed map does not contain a first entry associated with a first location of the driver;
- interpolating using the plurality of the entries in the speed map and generating the first entry;
- and
- revising the first entry to include an offset value associated with the determined adverse condition.
A non-transitory machine-readable storage medium encoded with instructions executable by a hardware processor of a computing component of a vehicle, the machine-readable storage medium comprising instructions to cause the hardware processor to:
- receive a first user input to initiate speed control from a driver and initiating speed control;
- retrieve a speed map associated with the driver, wherein the speed map is generated using geographic speed limits and learned driver behaviors, the speed map comprising a plurality of entries, each entry comprising a speed limit and an offset value, wherein the offset value is determined by driver-defined offset values and the learned driver behaviors;
- determine the speed map does not contain a first entry associated with a first location of the driver;
- interpolate using the plurality of the entries in the speed map and generating the first entry;
- receive a second user input to record a speed limit and recording a current speed limit;
- revising the first entry to include the current speed limit;
- and
- automatically set a speed of the vehicle according to the first entry's speed limit and offset value.
