Abstract
Method and system that includes receiving data about (1) a driver's expected vehicle performance and (2) a difference between the driver's expected vehicle performance and an estimated actual vehicle performance, and based on the received data determining control signals for an electric drivetrain system to effect the driver's expected vehicle performance. A vehicle control system that incorporates one or machine learning functions to control a drivetrain that is decoupled from a driver.
Claims20
A computer implemented method for assisting a human driver to control operation of a vehicle, comprising:
- receiving, through one or more human-vehicle control interfaces, real time driver controls input data indicating a throttle input signal and a steering angle input signal;
- receiving, through one or more vehicle embedded sensor systems, real-time positional state data about the vehicle;
- computing, based on the throttle input signal, steering angle input signal, and real-time positional state data a driver's expected vehicle performance;
- computing, based on the real-time positional state data, an actual vehicle performance;
- computing, based on the driver's expected vehicle performance and a difference between the driver's expected vehicle performance and the actual vehicle performance, control signals for an electric drivetrain system of the vehicle;
- applying the control signals to the electric drivetrain system to control real-time operation of the vehicle.
A vehicle control system for assisting a human driver to control operation of a vehicle, the vehicle control system comprising one or more processors and one or more memories storing software instructions that, when executed by the one or more processors, configure the vehicle control system to perform a method comprising:
- receiving, through one or more human-vehicle control interfaces, real time driver controls input data indicating a throttle input signal and a steering angle input signal;
- receiving, through one or more vehicle embedded sensor systems, real-time positional state data about the vehicle;
- computing, based on the throttle input signal, steering angle input signal, and real-time positional state data a driver's expected vehicle performance;
- computing, based on the real-time positional state data, an actual vehicle performance;
- computing, based on the driver's expected vehicle performance and a difference between the driver's expected vehicle performance and the actual vehicle performance, control signals for an electric drivetrain system of the vehicle;
- applying the control signals to the electric drivetrain system to control real-time operation of the vehicle.
A vehicle comprising:
- an electric drivetrain system for propelling and steering the vehicle along a surface;
- a human-vehicle control interface that includes a throttle control input and a steering control input for receiving real time driver controls input data indicating a throttle input signal and a steering angle input signal, respectively;
- a plurality of vehicle embedded sensor systems for sensing real-time positional state data about the vehicle;
- and
- a vehicle control system for assisting a human driver to control operation of the vehicle, the vehicle control system comprising one or more processors and one or more memories storing software instructions that, when executed by the one or more processors, configure the vehicle control system to perform a method comprising:
- receiving real-time throttle input signals and steering angle input signals from the human-vehicle control interfaces;
- receiving real-time positional state data about the vehicle from the vehicle embedded sensor systems, real-time positional state data about the vehicle;
- computing, based on the throttle input signal, steering angle input signal, and real-time positional state data a driver's expected vehicle performance;
- computing, based on the real-time positional state data, an actual vehicle performance;
- computing, based on the driver's expected vehicle performance and a difference between the driver's expected vehicle performance and the actual vehicle performance, control signals for an electric drivetrain system of the vehicle;
- applying the control signals to the electric drivetrain system to control real-time operation of the vehicle.
