AI Technical Summary
Technical Problem
Existing single-pedal driving systems in vehicles lack natural feel and predictability in regenerative braking, and are limited in applicability to only battery electric vehicles.
Method used
A vehicle throttle control system that generates braking force based on the integral and derivative of throttle position, using sensors and a control unit to determine a braking force request signal, allowing intuitive and predictable braking, applicable to a wider range of vehicles.
Benefits of technology
Enhances braking safety and predictability, enabling a more reliable single-pedal driving experience across various vehicle types by integrating throttle control with braking, optimizing energy recovery and minimizing energy waste.

Abstract
The present invention relates to a vehicle, and more particularly to an electric vehicle comprising an electric powertrain and at least one, preferably electric, energy storage unit. The vehicle has a one-pedal driving system with at least one vehicle throttle control for controlling throttle output and at least a portion of the vehicle's braking force. It also has at least one braking system that provides braking force to the vehicle. The braking force is at least partially based on a braking force request signal. The braking force request signal is determined based on the integral value of at least one measured variable of the vehicle throttle control. The present invention further relates to a single-throttle driving method for a vehicle, and a regenerative braking system for minimizing energy consumption to extend range, or minimizing tire wear, or brake wear, or minimizing particle emissions from tires, or particle emissions from brakes, or any combination thereof.
