Methods and systems automatically scale and set trailer brake gain without a need for vehicle driver input and without testing. Scaling a trailer brake gain of a trailer towed by a vehicle includes obtaining sensor data via one or more sensors of the vehicle, including from a hitch load sensor. A processor computes a trailer resistance force of the trailer based on the sensor data. The processor automatically updates the trailer brake gain based on both the sensor data and the trailer resistance force.

Methods and systems automatically scale and set trailer brake gain without a need for vehicle driver input and without testing. Scaling a trailer brake gain of a trailer towed by a vehicle includes obtaining sensor data via one or more sensors of the vehicle. A processor computes a trailer weight of the trailer and a trailer resistance force of the trailer. The processor automatically updates the trailer brake gain based on both the trailer weight and the trailer resistance force and may use vehicle data and axle torque.

Systems and methods associated with an electric vehicle are provided. The electric vehicle includes a sensor system, a communications system and a snow clearing system. The systems and methods detect, based on data from the sensor system, snow that may accumulate on a window of the electric vehicle. When snow is detected, a notification is provided, via the communications system, to a remote user device. The notification requests user acceptance of use of charge of a battery of the electric vehicle to operate the snow clearing system of the electric vehicle. The systems and methods receive, by the communications system, a response to the notification from the user device, and when the response indicates acceptance of the use of charge of the battery, the snow clearing system is activated. The snow clearing system is powered by the battery.

A vehicle parameter estimation module is configured to generate a first estimate of a vehicle parameter based on operating conditions of a vehicle measured or estimated at a first time. The vehicle parameter includes at least one of a tire cornering stiffness of the vehicle and an understeer coefficient of the vehicle. The vehicle parameter estimation module is also configured to determine an error value based on the first estimate of the vehicle parameter and values of the vehicle operating conditions measured or estimated at a second time that is later than the first time. The vehicle parameter estimation module is further configured to generate a second estimate of the vehicle parameter based on the first estimate of the vehicle parameter and the error value. A vehicle actuator control module is configured to control an actuator of the vehicle based on the second estimate of the vehicle parameter.
