Embodiments of the present application disclose a safety control method and a safety control system based on environmental risk assessment for an intelligent connected vehicle. The method includes: when a vehicle is in an automatic driving mode, acquiring environmental parameter information of the vehicle in a current driving environment; determining a target driving control parameter which meets a preset safe driving condition under the current environmental parameter; and managing a current automatic driving level of the vehicle by using the target driving control parameter.

A brake control system has an electronic control unit such that, when the motor vehicle is at a standstill, an automatic parking brake function can be activated by the control unit. In the presence of an activation condition for the parking brake function, the brake pressure required for this purpose can be determined at least in a manner dependent on the longitudinal inclination and in a manner dependent on an estimated normal force distribution of all of the wheels and/or an estimated capability of all of the wheels to transmit braking and/or drive torque to the underlying surface. Here, the brake pressure can be predefined to be higher the more wheels have a reduced normal force.

A steering control apparatus according to the present invention acquires a reference target torque, which is a torque regarding steering that is required to avoid an obstacle present ahead of a vehicle, determines a torque correction value for correcting the reference target torque based on specifications regarding running of the vehicle, determines a target torque based on the reference target torque and the torque correction value, and outputs a torque instruction for achieving the determined target torque to an actuator regarding the steering.

Techniques are described for determining weight distribution of a vehicle. A method of performing autonomous driving operation includes receiving two sets of values from two sets of sensors, where a first set of sensors measure weights or pressures applied on axles of a vehicle, and where a second set of sensors measure pressures in tires of the vehicle. The method performs an error detection and removal operation to remove or filter out any erroneous values from the two sets of values to obtain two sets of filtered values. The method determines one or more values that describe a weight or pressure applied on the axle to obtain the weight distribution of the vehicle based on the first set of filtered values or the second set of filtered values. Based on the obtained weight distribution of the vehicle, the method can determine a driving operation of the vehicle.

The present invention provides a vehicle control device capable of enhancing the ability of reducing or avoiding collision damage in a vehicle where a behavior of the vehicle when a braking operation is performed is largely influenced corresponding to a state of load (a loaded state), for example.

The vehicle control device includes: a travelability determination unit 300 configured to determine whether or not a vehicle 1 is travelable in an area disposed ahead of the vehicle on left and right sides of the vehicle; a deflection estimation unit 200 configured to estimate deflection of the vehicle 1 due to generation of a brake force applied to the vehicle 1; and a braking control unit 800 configured to calculate deceleration and deceleration start timing based on a distance between the vehicle 1 and an obstacle ahead of the vehicle 1 and a relative speed of the vehicle 1 to the obstacle, and configured to change at least one of the deceleration and the deceleration start timing based on a travelability determination result acquired from the travelability determination unit 300 and a deflection estimation result acquired from the deflection estimation unit 200.

A load balance system including first and second load indicators visible outside of a vehicle having a bed, first and second load sensors configured to sense respective first and second load weights in respective first and second bed areas. The load balance system includes a controller in communication with the first and second load sensors and the first and second load indicators. The controller is configured to activate the first and second load indicators to generate the same first and second outputs in response to detection of respective first and second load weights that are less than a predetermined threshold value. The controller is configured to activate the first and second load indicators to generate different first and second outputs in response to the detection of respective first and second load weights when one of the first and the second load weights is above the predetermined threshold value.

A multi-operational land drone includes a vehicle body, one or more batteries, one or more sensors, and a removeable dashboard. The one or more batteries are disposed on a lower portion of the vehicle body. The one or more sensors are disposed on the vehicle body.

A surface characterization system includes an active suspension a system with a wheel controller to control a first and second wheel of a vehicle where the active suspension causes a difference in loading between the first and second wheel. The wheel controller may cause the first wheel to slow and receive a signal indicative of a change of state of the vehicle. The wheel controller may cause the second wheel to oppose the change of state caused by the first wheel. The surface characterization system may estimate tire-surface parameterization data associated with the first tire and a surface upon which the vehicle is located.
