A vehicle driving control method depending on a baby mode, may include, when the baby mode is activated, receiving information on a state of a vehicle seat, correcting a center state of charge (SOC) value of a battery of the vehicle based on the information on the state of the vehicle seat, determining a state of a transmission of the vehicle, and performing regenerative brake and brake pedal stroke (BPS) scale/filtering correction control or an electric vehicle (EV) mode and accelerator position sensor (APS) scale/filtering correction control based on the state of the transmission of the vehicle and the state of the vehicle seat.

The present invention obtains a controller and a control method capable of appropriately executing adaptive cruise control for a straddle-type vehicle while securing a driver's comfort.

In the controller and the control method according to the present invention, when braking forces are generated on wheels of the straddle-type vehicle during adaptive cruise control, in which the straddle-type vehicle is made to travel according to a distance from the straddle-type vehicle to a preceding vehicle, motion of the straddle-type vehicle, and the driver's instruction, at a braking start time point at which the braking force starts being generated on each of the wheels, braking force distribution between the front and rear wheels is brought into an initial state where the braking force generated on the rear wheel is larger than the braking force generated on the front wheel. Then, a distribution ratio for the front wheel in the braking force distribution between the front and rear wheels is increased with a lapse of time.

A rear automatic braking system is automatically overridden and released if the accelerator pedal is depressed with the rate of change which is greater than empirically determined threshold beyond a predetermined percentage of its travel for at least a predetermined length of time and if the vehicle's brake pedal is not depressed.

Vehicles and methods of operating vehicles are disclosed herein. A vehicle includes a main frame, a work implement, and a control system. The work implement is supported by the main frame and configured to carry a payload in use of the vehicle. The control system is supported by the main frame and configured to control operation of the vehicle. The control system includes a payload measurement system configured to provide payload input indicative of a variable payload carried by the work implement in use of the vehicle and a controller coupled to the payload measurement system.

An outdoor grounds maintenance vehicle is self-propelled by a hydrostatic traction drive system that provides dynamic braking to the vehicle without the need for separate service brakes acting on the wheels of the vehicle. An engine kill device can be manually actuated by the operator to access the dynamic braking of the traction drive system by reducing the speed of the prime mover that powers the pump of the traction drive system. This provides an auxiliary braking system that can be used in an emergency or on demand by the operator in the event the accelerator pedal does not properly control the pump swashplates. The operator can control the rate at which the auxiliary brake system reduces the speed of the prime mover to zero.

To check the functionality/leak-tightness of a brake-by-wire brake system, a motor-operated brake pressure transducer is actuated. In this case, a pressure medium would flow out into a reservoir via a master brake cylinder. A diagnostic valve is therefore provided between the master brake cylinder and the reservoir, which diagnostic valve is composed of a check valve and a restrictor connected in parallel with respect to the check valve. The outflow of pressure medium is limited by the restrictor. Because the gradient of the pressure dissipation can be calculated, a measured pressure build-up can be compared with that which is to be expected, and a determination of functionality/leak-tightness can be derived from the comparison.

Tone ring mounting structure for an antilock braking system comprising a wheel end assembly rotatable component having at least a first end surface and a first engagement mechanism extending radially and non-cantilevered from the rotatable component, and a tone ring having a second end surface and a second engagement mechanism extending radially from the tone ring. Connecting engagement of the first engagement mechanism of the wheel end assembly rotatable component and the second engagement mechanism of the tone ring affects movement of the second end surface in a direction toward the first end surface. The first engagement mechanism and the second engagement mechanism can be engageable threads. The first engagement mechanism can include lugs formed on the wheel end assembly rotatable component and the second engagement mechanism threads or wedge ramps engageable with the lugs. A corrosion resistant coating can be applied to components of the tone ring mounting structure.

A utility vehicle includes a frame and a plurality of ground-engaging members supporting the frame. Each of the plurality of ground-engaging members is configured to rotate about an axle. The utility vehicle further includes a powertrain assembly supported by the frame and a braking system configured to operate in a normal run mode and an anti-lock braking mode. The braking system includes an anti-lock braking control module operably coupled to the plurality of ground-engaging members and configured to automatically engage the anti-lock braking mode in response to a predetermined condition.

Anti-skid control is performed by switching between a reduction mode for reducing braking torque and an increase mode for increasing braking torque based on a comparison between four wheel speeds and vehicle body speed. A controller calculates wheel accelerations based on wheel speeds and includes a control mode condition where the reduction mode is selected at each wheel and a wheel acceleration condition where each wheel acceleration is within a predetermined value range. If a state in which the control mode condition and the wheel acceleration condition are simultaneously satisfied is maintained over a predetermined time period, the controller determines that a residual state is satisfied. When the residual state is not satisfied, the controller calculates vehicle body speed based on the maximum value of the wheel speeds, whereas when the residual state is satisfied, the controller calculates vehicle body speed based on the minimum value of the wheel speeds.
