A method for dynamically determining a mass of a vehicle including a propulsion system coupled to a drive wheel is described, and includes monitoring vehicle operating conditions, executing an event-based estimation method based upon the vehicle operating conditions to determine a first vehicle mass state, and executing a recursive estimation method based upon the vehicle operating conditions to determine a second vehicle mass state. A final vehicle mass is determined based upon the first and second vehicle mass states.

A system for estimating tire parameters for an off-road vehicle in real time, the system including a processing circuit including a processor and memory, the memory having instructions stored thereon that, when executed by the processor, cause the processing circuit to measure a position of the vehicle at a first time, determine, based on the position, motion characteristics of the vehicle, predict, based on the motion characteristics, a position of the vehicle at a second time, measure a position of the vehicle at the second time, and generate a tire parameter associated with the vehicle based on the predicted position and the measured position of the vehicle at the second time.

A vehicle includes a level difference detector and a running controller. The level difference detector is configured to detect a level difference. The running controller is configured to perform in parallel level-difference override suppression control to suppress erroneous start for override of the level difference and level-difference override support control to support override of the level difference.

A vehicle restart control apparatus includes a processor configured to generate an override torque according to the environment information of the host vehicle when the vehicle is restarted after stopping; and a storage configured to store data and algorithms driven by the processor.

Disclosed are a device and a method for improving the fuel efficiency of a fuel cell vehicle in uphill and downhill driving. The device may calculate an appropriate stack output to be generated from a fuel cell stack based on the SOC of a battery as well as an uphill altitude at which the vehicle traveling on the uphill road has to travel further to reach the highest altitude when determining the degree of the stack output generated from the fuel cell stack when driving on the uphill road, and may prevent fuel consumption from increasing to generate excessive stack output while driving on an uphill road or the durability of the fuel cell stack from being deteriorated.

Example methods and systems for controlling speeds of a vehicle may generally determine a target vehicle acceleration using an autonomy control module of the vehicle. The target vehicle acceleration may be determined based upon at least one of a target vehicle following distance, a target vehicle following speed, or a target vehicle speed. The determined vehicle acceleration may be mapped to a level of vehicle torque using a vehicle dynamics module of the vehicle. Additionally, the level of vehicle torque may be applied to one or more wheels of the vehicle.

A vehicle control system determines that a vehicle is not fully loaded with a payload, determines an upper limit on engine propulsion power for the vehicle that is not fully loaded with the payload, and reduces an engine speed of the vehicle to a determined speed at which a power capability of an engine of the vehicle matches the upper limit on the engine propulsion power of the vehicle.

A method of estimating a load on a vehicle (10), the method comprising: obtaining a first load estimate using a first load estimation technique; obtaining a second load estimate using a second load estimation technique; analysing characteristics of the first load estimate and the second load estimate; and, based on the analysis selecting either the first load estimate or the second load estimate as an output load estimate.

An electrified fire fighting vehicle includes a battery pack, an electromagnetic device, an engine, and a controller. The controller is configured to monitor a state-of-charge of the battery pack, operate the electromagnetic device using stored energy in the battery pack to provide a performance condition including (i) accelerating the electrified fire fighting vehicle to a driving speed of at least 50 miles-per-hour in an acceleration time and (ii) maintaining or exceeding the driving speed for a period of time, and start and operate the engine in response to a start condition to facilitate reserving sufficient stored energy in the battery pack such that the state-of-charge is maintained above a minimum state-of-charge threshold that is sufficient to facilitate the performance condition. The acceleration time is 30 second or less. An aggregate of the acceleration time and the period of time is at least 3 minutes.

A vehicle control device 1 having: a deceleration detection unit 121 that detects deceleration of a vehicle T; a vehicle stop schedule identification unit 122 that identifies that the vehicle T is scheduled to stop; a brake control unit 123 that starts to reduce brake pressure when the speed of the vehicle T has dropped to or below a threshold value; and a threshold value determination unit 124 that determines the threshold value such that the threshold value increases the greater the deceleration detected by the deceleration detection unit 121 after the vehicle stop schedule identification unit 122 has identified that the vehicle T is scheduled to stop.
