Abstract: A control unit for preventing rollover of a tipper truck on inclined surfaces is disclosed. The control unit is configured to: receive sensor data from one or more vehicle sensors, wherein the sensor data includes a lateral inclination angle, establish compliance or non-compliance with a safety protocol, wherein compliance with the safety protocol is established if the lateral inclination angle does not exceed a predefined lateral inclination angle threshold, which represents a maximum allowable lateral inclination angle; abort tipping operation in response to non-compliance with the safety protocol; and adjust suspension systems in response to compliance with the safety protocol, such that a suspension adjustment angle counteracts the lateral inclination angle, and proceed with tipping operation once the suspension adjustment angle has compensated for the lateral inclination angle.

Abstract: The present disclosure relates to an air supply control arrangement for a heavy-duty vehicle including a lift axle which comprises a brake chamber. The air supply control arrangement includes a control valve and a lever. The control valve has a closed first state in which pressurized air along an air supply passage is blocked by the control valve, and an open second state in which pressurized air is allowed to pass through the control valve along the air supply passage. The lever has a first portion connected to the control valve and a second portion connectable to the lift axle so that when the lift axle is raised from its ride condition to its lift condition the lever moves the control valve from the open second state to the closed first state. When the lift axle is lowered to its ride condition the lever moves the control valve back to the open second state.

Abstract: A parking brake control arrangement for controlling operation of a parking brake of a vehicle, configured to: receive a first indication of whether or not a driver of the vehicle is present in a driver's seat of the vehicle; receive a second indication of whether or not the vehicle being in motion; receive a third indication of whether or not the vehicle is in a towing mode; and control, when the first indication indicates that the driver is absent from the driver's seat, the second indication indicates that the vehicle is in movement, and the third indication indicates that the vehicle is not in the towing mode, the parking brake of the vehicle from a disengaged state to an engaged state.

Abstract: An air supply control arrangement for a heavy-duty vehicle comprising a lift axle includes a brake chamber. An electronically controlled brake valve device allows pressurized air to be passed to the brake chamber of the lift axle. A pressurized air source supplies pressurized air to the electronically controlled brake valve device along a supply passage. A pilot control valve provided between the pressurized air source and the electronically controlled brake valve device can restrict air flow through the supply passage. A pressure-responsive element actuates the pilot control valve when the pressure in the lift bellow is increased so that the lift axle is raised to a lift condition. The pressure-responsive element closes the pilot control valve. When the pressure in the lift bellow is reduced so that the lift axle is lowered to a ride condition then the pressure-responsive element is deactivated to allow opening of the pilot control valve.

Abstract: An air supply control arrangement for a heavy-duty vehicle including a lift axle which includes a brake chamber. The air supply control arrangement includes a valve configured to be arranged in an air supply passage that enables pressurized air to be supplied from a pressurized air source to a brake chamber of a lift axle of a heavy-duty vehicle; a processing circuitry configured to receive measurement values of the pressure inside a tire of the lift axle, wherein the processing circuitry is configured to, based on the received measurement values, determine whether the lift axle is in its raised lift condition or in its lowered ride condition, wherein the processing circuitry is configured to control the valve to move to a closed state upon determination that the lift axle has been raised from its ride condition to its lift condition, thereby preventing pressurized air from reaching the brake chamber.

Abstract: An air supply control arrangement for a heavy-duty vehicle comprising a lift axle is provided. An electronically controlled brake valve device allows, when open, pressurized air to be passed to the brake chamber of the lift axle. A pressurized air source supplies pressurized air to the electronically controlled brake valve device along a supply passage. A pilot control valve provided between the pressurized air source and the electronically controlled brake valve device can restrict air flow through the supply passage. A pressure-responsive element actuates the pilot control valve when the pressure in the lift bellow is increased so that the lift axle is raised to a lift condition. The pressure-responsive element closes the pilot control valve. When the pressure in the lift bellow is reduced so that the lift axle is lowered to a ride condition then the pressure-responsive element is deactivated to allow opening of the pilot control valve.

Abstract: A parking brake system of a tipper vehicle having a tiltable tipper body is described. The system comprises a parking brake having a brake chamber which is pressurizable for releasing the parking brake. A valve device is in fluid communication with the brake chamber, the valve device comprising an exhaust port. The valve device has an activated state in which the brake chamber is in fluid communication with the exhaust port whereby air from the brake chamber is discharged, thereby applying the parking brake, and an inactivated state in which said fluid communication is disconnected. Upon receipt of a tipping signal, a neutral gear signal and a low speed signal, and upon detecting that the parking brake is still in the released state, the valve device is changed from the inactivated state to the activated state in order to exhaust air from the brake chamber, causing the parking brake to become changed to the applied state.

Abstract: One example described herein includes a system that can receive values for performance factors associated with a distributed storage system. The system can provide the values as input to a machine-learning model configured to select a hash function from among a set of hash functions based on the values and generate an output indicating the hash function. The system can then configure the distributed storage system to map a data item to a storage device using the hash function.

Abstract: A system, method, and computer readable medium train machine learning model using server parameters corresponding to a plurality of servers. The training produces an optimized feature set of the machine learning model. The system, method, and computer readable medium assign a server class to a received request based on the optimized feature set. The system, method, and computer readable medium compute, based on the optimized feature set, estimate response times for one or more servers from the plurality of servers corresponding to the server class. The system, method, and computer readable medium forward the request to one of the one or more servers based on the estimate response times.
