Regenerative braking control system that adjusts regenerative braking settings based on driving environment condition
View Patent ↗A regenerative braking control system for a vehicle can include three switches located in a cabin of the vehicle. The three switches can correspond to three regenerative braking settings. The three regenerative braking settings can correspond to low, medium, and high amounts of regenerative braking torque to apply to one or more wheels of the vehicle. The regenerative braking control system can include a processor operatively connected to the three switches. The processor can be configured to detect a condition. The condition can include one or more driving environment conditions. Responsive to detecting the condition, the processor can be configured to cause the amount of regenerative braking torque for one or more of the three regenerative braking settings to be adjusted based on the condition.
