A method includes instructing a vehicle to autonomously navigate to a given parking space from among the plurality of parking spaces, setting the given parking space to an occupied state in response to the vehicle being positioned within the given parking space, and obtaining infrastructure sensor data from an infrastructure sensor. The method includes determining whether the given parking space has transitioned from the occupied state to the unoccupied state based on the infrastructure sensor data, and in response to determining the given parking space has transitioned to the unoccupied state: obtaining location data from the vehicle, determining whether the vehicle is located at a predefined location based on the location data, and instructing the vehicle to perform a vehicle intrusion routine in response to the vehicle not being located at the predefined location.

System and method for detecting vehicle intrusions

A system and method for collaborative sensing metrics map generation, includes receiving sensing metric datasets from a first plurality of vehicles for each of a plurality of nodes having an assigned region for an area of interest. For each node, a determination is made whether a first threshold number of sensing metric datasets have been received in a last predetermined time window sufficient to provide sensing metrics for the node. Upon expiration of a predetermined period, a sensing metrics map for the area of interest is provided based upon sensing metric datasets received in the last predetermined time window to a second plurality of vehicles.

Collaborative sensing metrics maps

A vehicle includes a controller programmed to generate a command to an electric machine to reduce a torque output rate after an accelerator pedal is tipped out based upon a vehicle speed value and a wheel acceleration torque value. The torque output rate is initially reduced at a first rate, and is then reduced at a second rate slower than the first rate when the wheel acceleration torque value is greater than 0 Nm.

Control of accelerator lift-pedal deceleration in an electric vehicle

A vehicle includes a powertrain having an electric machine configured to power driven wheels, an accelerator pedal, and friction brakes. A vehicle controller is programmed to, with the vehicle being in a one-pedal driving mode: in response to a braking torque capacity of the powertrain exceeding a target braking torque that is based on a position of the accelerator pedal, command a torque, that is equal to the target braking torque, from the powertrain such that the vehicle is slowed using the powertrain without application of the friction brakes, and, in response to the braking torque capacity of the powertrain being less than the target braking torque, command torques from the powertrain and the friction brakes such that the target braking torque is satisfied and the vehicle is slowed using the powertrain and the friction brakes.

Vehicle braking controls and methods

Responsive to accelerator pedal release and a speed of a vehicle being less than a threshold in a presence of indication that available powertrain torque has been reduced for at least a predetermined period of time during an absence of brake pedal engagement, a controller operates friction brakes to bring the vehicle to a stop. Responsive to accelerator pedal release and the speed being less than the threshold in an absence of the indication that available powertrain torque has been reduced and brake pedal engagement, the controller operates an electric machine and not the friction brakes to bring the vehicle to a stop.

Brake assist during vehicle one pedal drive

Methods and systems are provided for limiting requested wheel torque during startup of a vehicle having an electrified powertrain. In one example, a method may include, responsive to a discharge power currently available being less than or equal to a threshold discharge power, operating the vehicle while requesting the wheel torque at a feedforward torque limit, the feedforward torque limit being based on the discharge power and a threshold vehicle speed. In this way, large shifts in wheel torque may be avoided upon startup of the vehicle, thereby reducing noise, vibration, and harshness at the electrified powertrain.

Feedforward torque limit for electrified powertrain

According to one embodiment, a vehicle includes an electrified propulsion system having an electric machine powered by a traction battery over an electrical distribution system (EDS). A controller is programmed to, reduce a speed limit of the vehicle from a maximum speed limit to an EDS speed limit in response to a measured average current of the EDS being within a threshold percentage of an average current limit of the EDS, and, in response to a measured speed of the vehicle exceeding the EDS speed limit, command a torque to the electric machine that is less than a driver-demanded torque such that the vehicle is propelled at a speed below the EDS speed limit.

Filtered battery current based vehicle speed limiter

A vehicle includes a powertrain and a controller. The controller, responsive to a parameter indicative of a grade on which the vehicle is travelling having a value greater than a threshold, and a given accelerator pedal input, commands the powertrain to produce an amount of drive torque for the vehicle that is based on the value.

Grade-compensated torque production to propel vehicle during one-pedal drive

A vehicle includes an electric machine, a brake lamp, and a controller. The controller operates the electric machine to selectively brake the vehicle according to accelerator pedal input. The controller also activates the brake lamp responsive to the accelerator pedal input being less than a first threshold demand for at least a first predetermined period of time.

Vehicle brake light control during one-pedal drive

A controller, responsive to accelerator pedal release and a speed of the vehicle being less than a threshold, operates an electric machine to provide braking torque according to a predetermined speed versus time profile that defines a predetermined duration for the speed to become zero and a target speed for each time instant during the predetermined duration such that, for a given one of the time instants, the electric machine increases the braking torque responsive to the speed being greater than the target speed and decreases the braking torque responsive to the speed being less than the target speed.

One-pedal drive method to control vehicle speed to a stop using feedback powertrain torque controls

A vehicle includes an accelerator pedal, an electric machine, and a controller. The electric machine is configured to propel and brake the vehicle according to a one-pedal driving operation. The controller is programmed to, in response to depressing the accelerator pedal, command a desired torque to the electric machine. The controller is further programmed to, adjust the desired torque based on a gradient of a road surface that the vehicle is positioned on. The controller is further programmed to, in response to movement of the electric machine in a direction that is opposite to a desired direction while the adjusted desired torque is being applied, increase the adjusted desired torque by a compensation torque such that movement of the electric machine transitions to the desired direction.

One-pedal drive system for a vehicle

Responsive to a target charge level, a target charge completion time, and a maximum charge rate being sufficient to achieve the target charge level during an available charge duration defined by the target charge completion time, a controller charges the traction battery at a selected rate less than the maximum rate such that the traction battery continuously receives charge until occurrence of the target charge completion time and the traction battery achieves the target charge level at but not before the target charge completion time.

Vehicle direct current fast charging

A vehicle includes a powertrain having an electric machine configured to power driven wheels, an accelerator pedal, and a brake pedal. A controller is programmed to, in response to driver-demanded torque corresponding to a position of the accelerator pedal, selectively brake the vehicle via operation of the electric machine, in further response to a speed of the vehicle being greater than a threshold, limit a rate of change of the driver-demanded torque commanded to the powertrain based on a first rate limit, and, in further response to the speed being less than another threshold, limit a rate of change of the driver-demanded torque commanded to the powertrain based on a second rate limit that is higher than the first rate limit such that, for a given driver-demanded torque, acceleration and deceleration of the vehicle is more responsive than when the first rate limit is applied.
