A vehicle drive assistance system is provided, which includes a processor configured to execute a required driving ability estimating module to estimate a driver's driving ability required for driving a vehicle based on a traffic environment around the vehicle and drive assistance provided to the driver by the vehicle, a current driving ability estimating module to estimate a driver's current driving ability, and a changing module to reduce the required driving ability by performing reduction processing in which comprehension of the traffic environment by the driver is facilitated when the current driving ability is lower than the required driving ability.

A wheel loader includes a forward clutch, an accelerator pedal, a brake pedal, and a controller configured to control hydraulic pressure of hydraulic oil supplied to the forward clutch. The controller performs clutch hydraulic pressure control for reducing the hydraulic pressure of the hydraulic oil supplied to the forward clutch according to an operation amount of the brake pedal on condition that at least the brake pedal is operated while the accelerator pedal is being operated. The controller continues the clutch hydraulic pressure control even after the clutch shifts from a complete engagement state to a semi-engagement state by the clutch hydraulic pressure control.

A motor vehicle control system that includes a first user-operable transmission selector for selecting a transmission operating mode and a user-operable gear selector, such as paddle input controls. The gear selector is operable in a first functional mode to select between a plurality of forward direction gear ratios. The gear selector is also operable in a second functional mode to select between a forward direction and reverse direction. This allows a user to use the gear selector to control travel in forward and reverse directions.

When having determined that an operation of an accelerator operator is initiated at a first timing and the operation amount continues to increase until a second specific timing arrives to become constant at a second timing, vehicle control means which a vehicle control apparatus comprises executes driving force control in such a manner that a time-differential value of controlled driving force during a first period from the second timing to a first terminal timing matches with a time-differential value of controlled driving force at the second specific timing as well as executes braking force control in such a manner that a time-differential value of the controlled braking force during the first period becomes a value more than or equal to a sum of a time-differential value of the controlled braking force at the second specific timing and a time-differential value of operation driving force at the second specific timing.

A controller for a motor vehicle includes means for receiving information indicative of a current vehicle speed; means for receiving information indicative of an amount of brake force a braking system is developing or is capable of developing; means for receiving information indicative of a gradient of a driving surface on which the vehicle is driving; and torque transmission reduction means for causing a powertrain torque reduction operation to be performed in which the controller causes one or more components in a torque transmission path from a torque delivery device to driven wheels to assume a torque reduction condition in which torque transmission is reduced or substantially terminated. The controller is configured automatically to cause the torque reduction operation to be performed in dependence at least in part on the information indicative of current vehicle speed, information indicative of brake force amount and information indicative of driving surface gradient.

A method includes collecting sensor data from a sensor associated with a vehicle, storing the sensor data in a buffer associated with the sensor, wherein the buffer stores an amount of buffer data, analyzing the sensor data for a proximate event trigger. When the proximate event trigger is not detected, the method includes purging a portion of the sensor data exceeding the amount of buffer data. When the proximate event trigger is detected, the method includes stopping the purging of any of the sensor data and storing the sensor data of the buffer and the sensor data associated with the proximate event trigger, and sending the sensor data of the buffer and the sensor data associated with the proximate event trigger to a server.

Systems and methods provide accurate determinations of relevant vehicle mass that can take into account any load being carried and/or towed by a vehicle, such as an electric vehicle or hybrid vehicle. Systems and methods also provide accurate road load measurements that can take into account road gradient(s) and the impact of gravity. Accordingly, the dynamic nature of relevant vehicle mass and road load can be captured. Efforts to optimize operation and/or take preemptive action to provide more efficient performance, enhance the drive experience, etc. can be better achieved through the more accurate determinations of relevant vehicle mass and road load achieved by these systems and methods.

A module for providing control signals for a brake system of a vehicle which has a supply source, including: at least one interface to be connected to a compressed-air source; at least one interface to transmit the control signals to at least one processing unit for the purposes of generating brake pressures; wherein the module is configured to be provided with a supply by a further supply source. Also described are a related redundancy system, an electronically controlled brake system, and a method.

The present disclosure includes a system, method, and device related to data collection and communication related to after-market and external vehicle systems, such as towing systems, cargo carrying systems, trailer breakaway systems, brake systems, braking control systems, and the like. Data is sensed, processed, shared, and further leveraged throughout the discrete components of the system, and possibly via internet and other communications' links, to effect various beneficial actions with minimal driver/user interaction or intervention. In the same manner, data from the system may be used for diagnostic reasons, safety controls, and other purposes.

A vehicle control system receives signals from sensors on board a first vehicle and plural other, second vehicles. Based on the signals received from the sensors, the system determines a brake assessment of a brake system, where the brake assessment includes a state of health of the brake system and/or a location of interest of a leak in the brake system. The system controls movement of the first vehicle and the second vehicles relative to at least one remote vehicle system based at least in part on the brake assessment that is determined.
