Vehicle energy management system

An energy management system determines two or more fuel components that represent fuel consumption by a vehicle system completing a trip over one or more routes. A trip plan that designates operational settings of the vehicle system at one or more of different locations, different distances along the one or more routes, or different times is generated or modified. The trip plan is based on the fuel components. The fuel components include a delta elevation component of the one or more routes, a delta speed component of the trip, a mean drag component of the vehicle system, a curvature component of the one or more routes, a base fuel component of the vehicle system, a minimum braking component of the vehicle system, a braking auxiliaries component of the vehicle system, and/or a drag variation of the vehicle system.

VEHICULAR DRIVING ASSIST SYSTEM RESPONSIVE TO DRIVER HEALTH MONITORING
20220363253 · 2022-11-17 ·

A vehicular occupant health monitoring system includes a heartbeat sensor disposed at a vehicle and operable to capture sensor data measuring an aspect associated with the heart of an occupant of the vehicle. A control includes a processor operable to process sensor data captured by the heartbeat sensor and provided to the control. The vehicular occupant health monitoring system, responsive to processing by the processor of sensor data captured by the heartbeat sensor, determines whether the measured aspect associated with the heart of the occupant is abnormal. The vehicular occupant health monitoring system, responsive to determining the measured aspect associated with the heart of the occupant is abnormal, controls a function of the vehicle.

Longitudinally guiding driver assistance system in a motor vehicle

A longitudinally guiding driver assistance system in a motor vehicle has a first detection system for detecting currently applying events or relevant events lying ahead, which require a change of the permissible maximum speed, a second detection system for detecting the course of the route, and a function unit which, when detecting a relevant event while taking into account the location of the relevant event, determines a location-dependent point in time, whose reaching causes the function unit to initiate an automatic adaptation of the currently permissible maximum speed or an output of a prompt information for permitting an automatic adaptation of the currently permissible maximum speed to anew permissible maximum speed. The function unit is designed to take into account available information concerning the course of the route when determining the location-dependent point in time.

Reconfigurable throttle-by-wire pedal subsystem for a vehicle and associated methods

The embodiments described herein concern a reconfigurable throttle-by-wire pedal subsystem for a vehicle and associated methods. One embodiment detects a pedal error in which a driver of the vehicle mistakenly actuates an accelerator foot pedal unit of the vehicle instead of a separate brake pedal of the vehicle, the accelerator foot pedal unit controlling a throttle of the vehicle, and performs the following in response to the detected pedal error: reconfiguring the accelerator foot pedal unit to control a braking subsystem of the vehicle instead of the throttle and reconfiguring a haptic feedback of the accelerator foot pedal unit from a throttle-by-wire mode to a brake-by-wire mode.

System and Method for Automated Off-Road Speed Control for a Vehicle
20230045864 · 2023-02-16 ·

A method of providing automated control of vehicle speed in a driver assist mode may include receiving an operator selection of the driver assist mode and a target speed, monitoring vehicle speed, and generating a propulsive torque request and a braking torque request based on a difference between the target speed and the vehicle speed. The method may further include, responsive to vehicle speed being in a selected range from zero to about three miles per hour, initiating a low speed correction to automatically provide a variable modification to the propulsive torque request or the braking torque request.

Method for limiting the speed of a motorcycle

Disclosed is a solution to the use of a speed limiter in a motorcycle that has a high capacity for acceleration, including a method for limiting the speed of a motorcycle using precise parameters of speed, acceleration and required engine torque and a single control button to manage the smart activation and deactivation of the limiter and to input new speed limits V.sub.lim in a simple way. It thus allows the use of a speed-limiting system in a motorcycle that has a high power/weight ratio by avoiding the sources of interference with the riding and the effects liable to jeopardize its stability.

System and method for controlling a vehicle

A vehicle control system determines an upper non-zero limit on deceleration of a vehicle to prevent rollback of the vehicle down a grade being traveled up on by the vehicle. The upper non-zero limit on deceleration is determined by the controller based on a payload carried by the vehicle, a speed of the vehicle, and a grade of a route being traveled upon by the vehicle. The controller is configured to monitor the deceleration of the vehicle, and to automatically prevent the deceleration of the vehicle from exceeding the upper non-zero limit by controlling one or more of a brake or a motor of the vehicle. The controller also is configured to one or more of actuate the brake or supply current to the motor of the vehicle to prevent rollback of the vehicle while the vehicle is moving up the grade at a non-zero speed.

Autonomous Machine Operation Using Vibration Analysis
20230101825 · 2023-03-30 · ·

Operating an autonomous machine using analysis of machine vibration while it is operational. Accelerometers are used to measure the machines vibrations while it is being operated. If the vibrations exceed a predetermined acceleration a controller adjust the velocity of the machine to prevent/reduce further vibrations.

Using ISA system to decelerate truck upon entering geofenced area

A method of decelerating a vehicle upon entering a halt zone includes determining a location of a vehicle at routine intervals while the vehicle is traveling along a road; determining when the vehicle enters a halt zone; and upon determining that the vehicle has entered a halt zone, limiting a speed of the vehicle to a nominal speed. The method preferably is performed by an intelligent speed adaptor (ISA) system of a vehicle. The vehicle preferably is part of a fleet of commercial vehicles, and a fleet manager preferably is notified when a vehicle has entered a halt zone.
