Systems and methods for detecting a brake event of a vehicle. One system includes an electronic control unit configured to receive a plurality of vehicle signal inputs, wherein the plurality of vehicle signal inputs includes an engine torque, and estimate a wheel torque of a rear wheel of the vehicle based on one or more of the plurality of vehicle signal inputs. The electronic control unit is also configured to determine a difference between the estimated wheel torque and the engine torque, and, in response to the difference being negative and a fault being detected in a brake switch associated with a brake of the rear wheel, activating a brake light of the vehicle.

Brake application detection

A system generates haptic feedback in an electric vehicle. The system comprises a frame, an energy storage device, and a wheel rotatably coupled to the frame. A motor receives power from the energy storage device and provides torque to the wheel. A controller determines a first operational state of the electric vehicle and transmits a first torque signal to the motor to control the motor to transmit first torque levels to the wheel to propel the electric vehicle. The controller determines a second operational state of the electric vehicle and transmits a second torque signal to the motor assembly. The motor assembly transmits second torque levels to the wheel to generate haptic feedback. The second torque signal is based on the second operational state of the electric vehicle and a torque profile stored in the memory, where the torque profile defines an irregular-shaped periodic waveform (e.g., a heartbeat rhythm).
