Abstract
Methods and systems are provided for an evaporative emissions system diagnostic. In one example, a method may include adjusting a controller operation in response to a fuel tank volume. A vehicle may determine sunrise and sunset times via a wireless modem and may relay the sunrise and sunset times to other vehicles within a threshold distance.
Claims18
A method comprising:
- alternating a controller between wake and sleep to start and stop an emission test in response to a fuel tank volume during a sunrise or a sunset;
- and
- providing sunrise and sunset times via a vehicle of a plurality of vehicles, wherein each vehicle of the plurality of vehicles comprises a dedicated-short-range communication network, and wherein the vehicle is the only vehicle of the plurality of vehicles comprising one or more of a wireless modem and a solar cell.
A system comprising:
- a plurality of vehicles each comprising a dedicated-short-range-communication network, wherein at least one vehicle of the plurality of vehicles is the only vehicle comprising a wireless modem and a different vehicle comprises a solar cell;
- a controller with computer-readable instructions stored on non-transitory memory thereof that, when executed, enable the controller to:
- retrieve times for a sunrise and a sunset for the at least one vehicle;
- relay times from the at least one vehicle to other vehicles of the plurality of vehicles;
- and
- execute an emission test during the sunrise or the sunset.
3 more elements
A method comprising:
- wirelessly retrieving information related to timepoints in a diurnal cycle where an ambient temperature is maximally rising and maximally dropping via a wireless modem in a vehicle;
- and
- wirelessly sending a request from the vehicle to one or more other vehicles located within a threshold distance of the vehicle to schedule an evaporative emissions system diagnostic at one or more of the timepoints via a dedicated-short-range-communication network.
