Abstract:
An example method of controlling an electrified vehicle includes activating a coast switch to a place an electrified vehicle in a coast mode.
Abstract:
Methods and systems are provided for detecting air-fuel ratio imbalances across all engine cylinders. In one example, a method (or system) may include indicating cylinder imbalance based on each of the exhaust air-fuel ratio, exhaust manifold pressure, and cylinder torque weighted by a confidence factor, where in the confidence factor is determined based on operating conditions.
Abstract:
A vehicle may require an electric recharge. A request may be sent to obtain identification of charge locations along a route. Along with the request, data may be sent identifying vehicle location, route, and desired safety rating. A response may be obtained from a remote server, and the results may be displayed, which include the safety rating of the charge station. The desired safety rating may be adjusted based on the battery's state of charge (SOC). The desired safety rating, for example, may be decreased as the battery state of charge decreases.
Abstract:
An exemplary method of controlling flow through a battery pack includes, in a first operating condition, moving flow through a first section of an enclosure using a first fan, and moving flow through a second section of the enclosure using a second fan. In a second operating condition, the method moves flow through the second section using the first fan.
Abstract:
A vehicle includes an electric machine configured to recharge a battery through regenerative braking, an electric heater configured to heat a powertrain lubricating oil, and a controller. The controller, in response to a temperature of the powertrain lubricating oil being less than a threshold, directs regenerative braking power to the electric heater.
Abstract:
A method according to an exemplary aspect of the present disclosure includes, among other things, controlling an electrified vehicle by increasing lift pedal regeneration in response to exceeding a system regeneration limit.
Abstract:
Methods and systems are provided for addressing engine cold-start emissions while an exhaust catalyst is activated. In one example, a method for improving exhaust emissions may include flowing ionized air into an engine exhaust, downstream of an exhaust catalyst, to oxidize exhaust emissions left untreated by the catalyst. The approach reduces the PM load of the exhaust as well as of a downstream particulate matter filter.
Abstract:
Systems and methods for dynamically updating engine mechanical losses, driveline electrical losses, and a desired driveline speed are disclosed. In one example, the desired driveline speed may be adjusted based on efficiency of operating a driveline at a most efficient speed of three different driveline speeds. The system and method may allow a driveline to operate more efficiently as the driveline ages.
Abstract:
External data from a second computer external to a vehicle is received in an in-vehicle computer comprising a processor and a memory. At least one derived datum is generated from at least some of the external data. The at least one derived datum is used to make an adjustment to engine performance.
Abstract:
An example method includes decreasing the pressure within at least one tire of a vehicle when the vehicle is moving. The decreasing is in response to a condition change. An example assembly includes a sensor and a tire pressure controller that causes a decrease in a pressure within at least one tire of a vehicle in response to a first condition detected by the sensor.
