Abstract:
A control mechanism is provided for a vehicle braking system of the kind in which a pair of pressure modulating valves have their performance modified during vehicle cornering only so that the brake on the inboard wheel receives less pressure than the brake on the outboard wheel. The control mechanism comprises a member which has four points forming the corners of a trapezium. The first two points, which are at the ends of one of the parallel sides of the trapezium, are connected to the suspension, the third point is connected to the valves, while the fourth point is constrained from vertical movement. During normal travel the member rotates freely about the third and fourth points so that there is no input to the valves. However, in cornering the vehicle roll causes the first and second points to move differently so that the third point also tends to move so altering the performance of the valves.

Abstract:
A vehicle stop maintaining system comprises an automatic transmission, an automatic stop-restart mechanism for automatically stopping and restarting an engine, a foot brake mechanism for braking vehicle wheels through hydraulic brake mechanisms, a brake force control mechanism having a pressurizer that increases hydraulic brake pressure applied to the hydraulic brake mechanisms, and for braking the wheels by controlling the pressurizer independently from brake pedal depression, a controller configured to maintain a vehicle stopped state by operating the automatic stop-restart mechanism to stop the engine and operating the brake force control mechanism to keep initial hydraulic brake pressure according to the brake pedal depression, and a drive force state determining module for determining a drive force stabilized timing. The controller operates the automatic stop-restart mechanism to restart the engine and operates the brake force control mechanism to release the initial hydraulic brake pressure when accelerator pedal depression is detected.

Abstract:
A method for controlling a brake system of a motor vehicle wherein a central generation of brake-fluid pressure takes place electrically and essentially mechanically decoupled from the movement of a brake-actuating element. The brake pressure of individual wheels can be selectively modified depending on driving-dynamics parameters by activating hydraulic check-valve and drain-valve elements. In the case of braking events occurring before stability and/or slip limits are reached, which limits would make it necessary to use the antilock braking system and/or a stability program, the brake pressure is reduced such that the use of the hydraulic valve elements for the antilock brake system and/or the stability program is time-delayed. Further, blocking the supply of brake fluid to individual wheels or creating pressure-decrease states for individual wheels is minimized with respect to time.
Abstract:
A lean angle detection sensor detects a lean angle of a vehicle. A storage portion stores a second relationship that represents a ratio of a braking force of a front wheel brake to a target braking force for each lean angle and/or a third relationship that represents a relationship with a ratio of the braking force of a rear wheel brake to a target braking force for each lean angle. A ratio setter determines which second relationship to refer to among the second relationships stored in the storage portion based on a detection result input to a detection result input portion and/or determines which third relationship to refer to among the third relationships stored in the storage portion based on a detection result input to a detection result input portion. The ratio setter sets a ratio of the braking force of the front wheel brake and the braking force of the rear wheel brake based on the second relationship and/or the third relationship.
Abstract:
A control system (18) and method for an automotive vehicle (10) includes a roll rate sensor (34) for generating a roll rate signal, a lateral acceleration sensor (32) for generating a lateral acceleration signal, a longitudinal acceleration sensor (36) for generating a longitudinal acceleration signal, and a yaw rate sensor (28) for generating a yaw rate signal. A safety device or system (44) and the sensors are coupled to a controller. The controller (26) determines an added mass and the height of the added mass on the vehicle, or a roll gradient, a roll acceleration coefficient, and/or a roll rate parameter that take into account the added mass and height from the roll rate, the lateral acceleration, the longitudinal acceleration, and the yaw rate of the vehicle, and controls the safety system in response thereto.
Abstract:
A method for providing enhanced stability, control and management for a prime mover connected to an auxiliary vehicle is disclosed. An auxiliary vehicle is connected to a prime mover with an auxiliary stability enhancing system and an electronic stability enhancing system, including at least one processor with a memory having computer instructions stored thereon. The processor communicates with a plurality of sensors to detect force values and motions values, and communicates with database storage containing specifications and characteristics representing the prime mover and auxiliary vehicle to compare the force and motion values with the specifications to determine if any values exceed known preset threshold values for the prime mover and auxiliary vehicle. A calculated response, and a location for applying the response, is determined by using a computer model of the prime mover and auxiliary vehicle to reduce the detected force or motion value that exceeds the preset threshold value.
