Systems, devices, and methods are disclosed for determining whether to provide an over-the-air (OTA) update to a vehicle. An example method includes determining an update characteristic of a pending software update for a vehicle. The method also includes determining a vehicle battery state of charge (SOC) threshold based on the update characteristic. The method further includes modifying the threshold based on a location of the vehicle. The method still further includes determining a SOC of a battery of the vehicle. And the method yet further includes responsively providing the pending software update to the vehicle based on the SOC and the threshold.

A vehicle is provided which may include an energy conversion device, an energy source to supply power to the energy conversion device, and at least one controller in communication with an interface. The controller may be programmed to output a distance to empty (DTE) to the interface based on conditions of vehicle components and the energy source compensated by a distance correction factor. The controller may further include a DTE prediction architecture including a feed-forward energy consumption estimator, an energy consumption learning filter, a distance compensator, and a DTE calculator. A method for estimating distance to empty for a vehicle is also provided which may output a DTE modified by a predicted DTE range loss selected to include a distance correction factor corresponding to and correcting for the noise factor.

A stop/start vehicle includes an engine and a stop/start system that prevents an auto stop of the engine when the speed of the vehicle is approximately zero in response to the vehicle being located at a service location or in response to the vehicle being located in a user identified geographic region.

An automotive vehicle includes engine start/stop (ESS) and adaptive cruise control with stop and go functionality (ACCS&G). A method of coordinating operation of the ESS and ACCS&G systems is provided. The ACCS&G system brings the vehicle to a stop. After a delay and satisfaction of autostop conditions, the ESS system stops the engine. Upon receipt of an input and satisfaction of start conditions, the ESS system restarts the engine. The ACCS&G system then resumes control of the restarted engine.
摘要:
A system and method for controlling engine idle stop in a hybrid vehicle that uses predictive information to schedule engine stops with relatively longer stop duration time to gain more fuel savings and extend life of starter motor. More specifically, predictive information may be used to determine potential vehicle stop events, along with corresponding stop duration times, within a time window. An engine stop scheduler and/or controller may be configured to schedule stops of longer duration for optimal total engine stop time. Similarly, taking into account constraints imposed by the thermal limits of the motor, engine stop may be inhibited for predicted short events to allow engine stop at later longer stop events.

A stop/start vehicle includes an engine and a stop/start system that selectively prevents an auto stop or auto start of the engine in response to a detected vehicle proximity and direction of travel relative to an emergency vehicle. The stop/start system may be programmed to prevent an auto stop of the engine in response to a detected proximity to an emergency vehicle where the emergency vehicle is traveling in the same direction as the stop/start vehicle, or in response to a detected proximity to an emergency vehicle where the stop/start vehicle is located within an intersection. The stop start system may also be programmed to prevent an auto start of the engine in response to the engine being stopped, and further in response to a detected proximity to an emergency vehicle where the emergency vehicle is traveling in cross traffic relative to the stop/start vehicle.

A system and method for controlling a start-stop system for an engine in a vehicle includes automatically stopping the engine with a transmission gear lever of the vehicle in DRIVE. The engine is automatically restarted when the vehicle is shifted out of DRIVE and at least one condition is met. The at least one condition includes a final position of the gear lever. Automatic restarting of the engine is suppressed when the vehicle is shifted out of DRIVE and at least one other condition is met; the at least one other condition also including a final position of the gear lever.
摘要:
A system and method for controlling a start-stop system for an engine in a vehicle includes automatically stopping the engine when the vehicle is in NEUTRAL and automatically restarting the engine when the vehicle is shifted out of NEUTRAL and at least one condition is met. The at least one condition may include the direction of movement of a transmission gear lever. Automatic restarting of the engine is suppressed when the vehicle is shifted out of NEUTRAL and at least one other condition is met. The at least one other condition may also include the direction of movement of the transmission gear lever.
摘要:
A power distribution box (PDB) includes relays to connect a vehicle battery to corresponding electronic control units (ECUs) of a vehicle. A processor is programmed to instruct the PDB via a control interface to cause one of the relays to power a target ECU, send a sleep command over a vehicle bus to cause powered ECUs other than the target ECU to sleep, and install a software update to the target ECU.

A system includes a processor controlling a vehicle module (VM) in communication with a telematics control unit (TCU) over a bus. In this embodiment, the processor is configured to receive an authentication request, including a counter value, from the TCU. The processor is also configured to respond to the authentication request based on comparison of the counter value to a stored counter value stored by the VM. The processor is further configured to receive a command corresponding to the authentication request and including the counter value, responsive to the approved authentication request and process the command based on comparison of the counter value to the stored counter value.
