    Abstract: An emergency brake assistance system includes: a collision risk detection unit (12) to detect a risk of collision with an object in front of the vehicle, based on data from an environment sensor (14) for recording objects in front of the vehicle and data from an accelerator sensor (16) for recording an intention to accelerate by the driver; and a collision avoidance unit (18) to implement measures to prevent a potential collision with the object in front of the vehicle, based on data from the collision risk detection unit. The system temporarily deactivates, for a specified time duration, an override condition of a safety concept of the system when the accelerator sensor records the driver's intention to accelerate and the vehicle speed is below a specified speed threshold. Thus the driver's acceleration command when setting the vehicle in motion temporarily cannot override an automatic actuation of the emergency brake system.

    Abstract: Provided is a brake control apparatus for a vehicle which detects an amount of brake-pedal operation by means of an electric signal, and then calculates a braking force demanded by a driver from the electric signal, and thereby generates the demanded braking force. A control mode for a braking force is switched from a normal control mode to a stationary-vehicle control mode, if a determination that the vehicle is in a stationary state is followed by another determination that an electric signal corresponding to an actual braking force exceeds a command value for a stationary-vehicle braking force while the vehicle is in the stationary state. The control mode for a braking force is switched from the stationary-vehicle control mode to the normal control mode, if it is determined that the demanded braking force becomes smaller than the command value for the stationary-vehicle braking force.

  • Patent number: 8554419
    Abstract: In the event that the brake pedal and accelerator pedal are depressed simultaneously, powertrain output is decreased monotonically with brake pedal input. In a lower range of brake pedal input, the brakes are prevented from actuating or are allowed to actuate minimally. In a higher range of pedal input, the powertrain output continues to be decreased and the brakes are allowed to actuate. In yet another higher range of pedal input, the powertrain output is substantially decreased such that a minimal powertrain output is achieved. The powertrain may include an internal combustion engine and/or an electric motor. The brake pedal input is determined based on a sensor associated with the brake pedal, the brake booster, or the master cylinder.

  • Patent number: 8070652
    Abstract: The present invention relates to a method for overcoming tooth butt conditions (ZaZ) when engaging gears in transmissions. A sensitive adjustment of the clutch to apply torque for rotating the drive shaft of the transmission in order to overcome tooth butt conditions has certain limits because of the proportion of the power required and desired for making said sensitive adjustment. This may cause unpleasant jerking of the vehicle or a clearly audible locking noise of the involved positively connected elements and undesired mechanical stress to said elements. The method according to the present invention provides a remedy due to the fact that during each shifting process, regardless of the occurrence of a tooth butt condition, the clutch is brought into a position allowing minimum predetermined torque transmission to the drive shaft of the transmission, and this torque is supported on a transmission brake, which is often already available.

  • Patent number: 8038575
    Abstract: A releasable backstopping clutch is provided with a safety mechanism to prevent uncontrolled release of the clutch. A support structure is fixed against rotation and releaseably coupled to the one of the inner or outer members of the backstopping clutch. The support structure inhibits rotation of the member when coupled to the member and permits rotation of the member when uncoupled from the member to release the clutch. A sensor is configured to generate a signal indicative of a characteristic associated with movement of the member and a controller is configured to cause recoupling of the support structure and the member if the characteristic meets a predetermined condition.

  • Patent number: 8010271
    Abstract: A brake control device for an electric vehicle includes an instruction controller, a pattern generator, and comparators. The instruction controller generates an instruction signal for instructing a motor about electric brake force. The pattern generator generates a first pattern signal for changing over electric brake force to machine brake force and a second pattern signal obtained by shifting the first pattern signal by a predetermined frequency. One of the comparators outputs, as an electric-brake force pattern, smaller one of the instruction signal and the first pattern signal. The other of the comparators outputs, as a notification signal, a signal output when the second pattern signal becomes equal to or smaller than the instruction signal.

  • Patent number: 7894958
    Abstract: A traction control system (30) for a machine (10) includes a driven wheel (22) operated by a motor that is controlled by an electronic controller (54). A speed sensor (44) measures the speed of the driven wheel (22), and communicates a wheel (22) speed to the electronic controller (54). A travel speed sensor (44) measures the travel speed of the machine (10) and communicates it to the electronic controller (54). A steering sensor (44) measures a displacement of the machine (10)'s steering system (28), and communicates a steering angle to the electronic controller (54). The electronic controller (54) calculates a speed ratio, based on the wheel (22) speed and the travel speed, and an expected slip ratio, based on the steering angle. The speed ratio is corrected by application of the expected slip ratio to yield a corrected speed ratio that is indicative of a slip condition. The operation of the motor is then adjusted to address the slip condition.

  • Patent number: 7826942
    Abstract: A method of generating braking information for a device including first and second sensors linked to a control unit and designed to sense positioning information concerning a brake pedal moving between released and depressed positions. The method includes transmitting to the control unit, by the first sensor, a first pedal “press” signal and a first “non-press” signal, and transmitting to the control unit, by the second sensor, a second pedal “press” signal and a second “non-press” signal. The method also includes the generation of a first information signal if the first pedal “press” signal and first “non-press” signal are inconsistent and a second information signal if the second pedal “press” signal and the second “non-press” signal are inconsistent, each signal being analyzed independently of the other for this generation.

  • Patent number: 7720589
    Abstract: A vehicle control device using brake hydraulic pressure includes a hydraulic unit having a housing and an electronic control unit having a casing. The housing of the hydraulic unit is mounted on a mounting surface of the casing of the electronic control unit so that the casing of the electronic control unit protrudes from the housing of the hydraulic unit to one side. On the protruding area of the casing, a bulge is formed in which a vehicle behavioral sensor is mounted. A control connector is also provided on the protruding area of the casing. The bulge does not protrude from the substantially square contour of the vehicle control device. Thus, the bulge will scarcely increase the installation space of the vehicle control device. A vehicle behavioral sensor is mounted on a small substrate.

  • Patent number: 7711469
    Abstract: A process and device for controlling the brake system of a motor vehicle with all-wheel drive are described. The process and the device include an electronic control unit which controls at least one coupling unit for engaging and disengaging an all-wheel drive, so that at least one wheel can be decoupled, from the drive. After stopping the motor vehicle, for example on a sloping roadway, a predefined brake pressure on at least one wheel of the motor vehicle is held either depending on or independently from the extent of brake pedal actuation. The brake pressure is held until a brake pressure reduction condition is present, such as during a brake pressure holding time. During that time, the brake pressure on at least the one wheel is reduced and the wheel is decoupled from the drive to detect slippage, while at least one other wheel remains pressurized with brake pressure.
