Title: Traction control for motor vehicle - derives constantly updated grip coefft. to control engine torque and wheel braking
Inventor: TSUYAMA TOSHIAKI
IPC: F02D29/02
Filed: 1991-06-21
Abstract: Each wheel is fitted with a wheel-speed sensor linked to a processor control. This computes the slip of a drive wheel by comparing the drive wheel speed with the speed of the driven wheels. The system computes a grip coefft. for each wheel and updates it by repeated measurements. The newly computed grip coefft. replaces the previous coefft. if it is different than the threshold value. If one drive wheel spins the torque is controlled until it and the other drive wheels are at the threshold slip level, as computed via the updated grip coefft. The wheel-speed is controlled by a combination of engine torque reduction and wheel braking. ADVANTAGE - Improved traction, processor control continuous update.

Title: Vehicle pneumatic tyre with upturned carcass cord layer folded-back -  giving gap in tread region for improved lateral stiffness, increased productivity and reduced weight
Inventor: IWAMURA WAKO
IPC: B60C15/00
Filed: 1991-09-18
Abstract: Vehicle pneumatic tyre in which the edge (P) of the upturned portion (10B) of the carcass cord layer (7A,7B) is folded back to form a second layer (11B) which extends round the bead (4) to the tread region. The edges (R) of the cord layer have between them an axial gap (L) and each overlaps (13) the thread cord layer (9) by at least 15 mm. The second cord layer (11A,11B) which is folded back may lie outside or inside the first layer (10A, 10B); in the latter case the end (R) of the layer is fastened between the first layer and the tread core layer (9). The bead region (5) may include an outwardly-taped filler strip (12) of hard rubber and the upturned portion of the cord layer may extend beyond this to the folding point (P), approximately at the point Q of greatest tyre section width. ADVANTAGE - The improved carcass construction gives reduced tyre wt., improved vehicle ride and improved productivity without impairing tyre lateral stiffness. In partic., the double layer sidewall and tread shoulder increases its stiffness and the lateral tyre stiffness, while a single carcass layer over most of the tread crown width does not increase tread stiffness undesirably. The absence of cord ends at the folding point (P) improves adhesion to the rubber.

Patent DE-4134781-A1 (DE)
Inventor: BITZER RAINER DIPL ING
IPC: H02N2/14
Filed: 1991-10-22
Abstract: According to a process for regulating the frequency of a travelling wave motor, a real value proportional to the real frequency of the exciting alternating voltage of the travelling wave motor (10) is deduced from the amplitude of an alternating voltage (sensing voltage) detected at the stator (11) of the travelling wave motor (10), this real value is compared with a set value proportional to the set frequency, and the exciting frequency is corrected with a deviation subjected to an appropriate regulating algorithm. In order to maintain the travelling wave motor (10) at a stable working state of maximum power, the set value is derived from the amplitude modulation of the sensing voltage. This set value is produced in a superimposed regulating circuit in which the sensing voltage is demodulated, rectified and compared with a predetermined amplitude modulation set value. The difference detected through this comparison is supplied to a regulator (21) whose regulated value taken at its output represents the set value.

Title: Compressed-air braking system esp. for heavy goods vehicle - includes electronic controller comparing brake cylinder pressures and correcting control valve signal for cylinder-specific pressure deviation
Inventor: STUMPE WERNER DIPL ING
IPC: B60T13/66
Filed: 1992-02-28
Abstract: The pressure in the brake cylinders (13,14) supplied via control valves (11,12) is measured by transducers (21,22) while a detector (40,50) on each wheel brake (9,10) signals contact between the lining (35) of the brake shoe (33,34) and the drum (37).

The measured pressures at the instants of contact are compared. Typical pressure deviation for each cylinder in subsequent braking operations is allowed for in a corrected signal to the corresp. valve. ADVANTAGE - Ride stability is improved, and heating and wear of brakes are reduced by simultaneous application on all braked wheels. Reduces coupling forces in tractor-and-trailer combinations.

Patent DE-4224971-A1 (DE)
Inventor: BUSCHMANN GUNTHER
IPC: B60T8/26
Filed: 1992-07-29
Abstract: In order to increase the reliability of a braking system with electronic control of the braking-force distribution, the invention calls for the front wheels (VR, VL) to be acted on, during braking, by a short pressure-reduction pulse which is negligible for the braking process, and the reaction of the front wheels to the pressure-reduction pulse is determined. If the reaction indicates an imbalance between, or a fault in, the front-wheel brakes, the limitation on the pressure increase in the brakes on the rear wheels (HR, HL), which is a result of the control of the brake-force distribution, is removed. The rear wheels thus provide, in this situation, an increased contribution to the braking process.
