The invention provides a meter display remaining oil quantity calculation method and device, and the method comprises the steps: carrying out the filtering processing of a real-time fuel resistance value, and obtaining a filtered resistance value; inquiring a first oil quantity value corresponding to the filtered resistance value from a preset corresponding relation between the resistance value and the oil quantity; state information of the vehicle is dynamically monitored to judge whether the vehicle enters a stable state or not, and a vehicle stable flag bit is generated; dynamically calculating an oil quantity correction coefficient based on the vehicle speed in the state information, the remaining oil quantity displayed on the surface at the previous moment and a reference oil quantity value; and based on the fuel quantity correction coefficient, the instantaneous fuel injection quantity and the reference fuel quantity value, the meter display remaining fuel quantity at the current moment is calculated. By dynamically capturing the reference fuel quantity in the stable state of the vehicle and fusing the real-time vehicle speed and the fuel injection quantity for correction, smooth and accurate display of the meter display fuel quantity in the driving process is achieved, abrupt change is effectively eliminated, and the reading credibility is improved.

This invention discloses a multifunctional high-toughness robot cable and its manufacturing process, relating to the field of cable technology. It includes a main power cable unit, comprising, from the inside out, a conductor assembly, an insulation layer, a shielding layer, a filling layer, an isolation layer, and a sheath layer. The conductor assembly comprises multiple graphene-reinforced silver-plated copper alloy conductor wires, each with a diameter of 0.05-0.10 mm. These conductor wires are bundled and twisted together to form a double-stranded structure, with a bundle pitch of 10-15 mm and a twist pitch of 20-30 mm, the twisting directions of which are opposite. The insulation layer is a gradient composite structure of silicone rubber and XLPE, consisting of an inner silicone rubber layer, a gradient transition layer, and an outer XLPE layer, from the inside out. The inner silicone rubber layer has a thickness of 0.3-0.5 mm, the outer XLPE layer has a thickness of 0.2-0.3 mm, and the gradient transition layer has a thickness of 0.05-0.1 mm. A functional layer is also included, positioned around the periphery of the main power cable unit, together forming the multifunctional high-toughness robot cable structure. The cable of this invention features high toughness, multifunctionality, and high market adaptability.
