A magnetostriction type torque sensor employs a plurality of detector coils arranged in axial arrangement along an objective rotary body. The detector coils are so designed and arranged as to compensate influence of temperature, particularly the error caused due to axial temperature gradient caused in the objective rotary body.

An engine spark timing controlling device using a resonant type vibration sensor having mechanical resonance characteristic near the knocking frequency of an engine. The vibration sensor is arranged on a body of an engine and the sensor output signal is processed and the spark timing is adjusted to obtain an optimum knocking condition.

An ignition timing control system for an internal combustion engine comprises first circuitry for producing a function of the intensity of combustion knock in each cylinder in a sequence, second circuitry for storing the function of each cylinder respectively in a memory circuit each of which corresponds to a specific cylinder, and third circuitry for determining the ignition timing of each cylinder by modifying the basic ignition timing determined by an advance mechanism, in accordance with the respectively stored functions.

A radar-operated collision avoidance system for a roadway vehicle comprises a radar device for sensing the vehicle speed relative to an object and its distance thereto to decide whether the vehicle is approaching the object at a dangerously high speed. A minimum allowable distance represented by a digital code is stored in a memory location within an array of rows and columns and read out in response to a sensed vehicle speed relative to the roadway and to a sensed magnitude of steering movement. The minimum allowable distance is compared with the distance sensed by the radar to determine that the decision is valid only when the latter is smaller than the former.

Trains of electrical pulses are produced at variable rates proportional to the vehicle and wheel speeds respectively and fed into a first and a second pulse counter, each producing its output upon counting of a predetermined number which is determined such that an optimum slip rate occurs when the outputs of these counters are produced at the same time. The output of these counters are utilized to operate and release an actuator which controls the flow of hydraulic pressure applied upon depression of a brake pedal to the wheels of a vehicle.
